In short
- Arrange insurance and complete the ownership transfer first, within Hungary's legal deadline.
- Book an early service with a full oil, filter and fluid change unless recent proof exists.
- Check every key, lock and code, and order a spare if only one key came with the car.
- Close out any faults noted at the pre purchase inspection while the price is still fresh.
The week after you buy a used car is when a sound purchase is either secured or quietly undermined. Ownership does not fully transfer on a handshake, insurance gaps carry real risk, and the previous owner's maintenance is an unknown until you reset it to a baseline you can trust. This post gives an ordered checklist for the first seven days, written for buyers in Hungary and especially English-speaking and expat owners. We cover insurance and the legal ownership transfer, an early service with a full fluid change, key, lock and code checks, and how to settle any faults that were flagged during a pre purchase inspection before they drift out of reach.
Sort insurance and ownership transfer first
The very first task is to make sure the car is legally insured in your name before it moves under its own power. In Hungary compulsory third-party liability cover, known as KGFB, follows strict rules, and the seller's policy does not simply pass to you. Contact an insurer or broker before collection so that cover is active for the drive home, and keep written confirmation with you. Driving even a short distance without valid liability insurance exposes you to serious penalties and personal liability for any damage you cause. Treat this as the gate that everything else in the first week must pass through.
Ownership transfer is the second half of the same task and is time-critical. A written sale contract, the adasveteli szerzodes, must be completed and signed in duplicate, and the change of keeper must be registered with the authorities within the legal deadline. The seller reports the sale, and you as buyer must register the transfer at a government office within fifteen days to avoid fines and to stop liability for road tax or offences resting with the wrong person. Bring identification, the contract, the vehicle documents and proof of valid insurance. Until this is done, the car is not fully yours on paper.
Completing the ownership transfer in Hungary
The registration is handled at a government customer office, and both parties benefit from acting quickly. The seller should submit their notification of the sale, while you register as the new keeper with the signed contract, your identity document and residence details. Expat buyers should confirm whether their residence card or address card is required, as this can affect processing. Once the transfer is recorded, a new registration certificate is issued in your name. Keeping copies of every signed page protects you if any dispute over the sale date arises later on.
Cover for the drive home and the first weeks
Arrange insurance to start from the moment of collection, not the day the paperwork clears, because the two can differ. Many insurers can issue immediate confirmation of compulsory liability cover, which is enough to drive the car legally home. Consider whether comprehensive cover suits the car's value and your circumstances, and check the excess and any restrictions on named drivers. Keep the confirmation accessible on your phone and on paper. If you collect the car outside the seller's home city, confirm that cover applies for that journey before you set off.
Book an early service and a full fluid change
Once the car is legally yours and insured, reset its mechanical condition to a baseline you can trust. Unless the seller supplied dated proof of a very recent service, book a full service early in the first week. Old engine oil that has done an unknown number of kilometres is the cheapest risk to remove, and fresh oil with a new filter protects the engine you have just paid for. Ask the workshop to record the mileage and date so your ownership starts from a clear reference point. From here every future interval is measured against a service you commissioned and can verify yourself.
A first service is also the moment to have several lifed fluids checked and renewed as needed, not just the engine oil. Brake fluid absorbs moisture over time, coolant loses its corrosion protection, and automatic gearbox oil degrades with heat, yet none of these show on a quick glance. If the history does not prove when they were last changed, assume they are due. Spending a modest sum now on fluids and filters is far cheaper than the components they protect. It also surfaces any early leak or worn part while you still have the seller's description fresh for comparison.
Engine oil, filter and gearbox fluid change
Have the engine oil and filter changed to the manufacturer's specification, and note the grade used on your record. On a car with an automatic or dual-clutch gearbox, ask whether the transmission fluid is due, since neglected gearbox oil is a common and expensive omission on used cars. Manual gearboxes and differentials also carry oil that is occasionally overlooked. Changing these early gives the drivetrain a clean start under your ownership and removes doubt about what the previous keeper did or skipped. Keep the old service records alongside your new invoice.
Brake fluid, coolant and other lifed fluids
Brake fluid should typically be renewed every couple of years regardless of mileage, because absorbed moisture lowers its boiling point and weakens braking under heavy use. Coolant has a service life too, and old coolant can allow internal corrosion in the engine and radiator. Ask the workshop to test the brake fluid moisture content and the coolant strength, and to top up or renew as needed. Power steering fluid and screen wash are minor by comparison but worth checking while the car is on the ramp. Record every fluid for your baseline.
Check every key, lock and security code
Keys and security are easy to overlook in the first week and awkward to fix later. Confirm how many keys came with the car and test every one, including any spare, on all functions: unlocking, locking, the boot release and the immobiliser. A car handed over with a single key is common, but a replacement coded key can cost a significant sum, so factor it in and order one early rather than discovering the gap when a key is lost. Check that the remote battery works and that central locking responds from a normal distance rather than only at the handle itself.
Physical locks and codes deserve the same attention. Try the key in every door lock and the boot, not just the driver's door, since seized barrels and worn cylinders are common on older cars and can leave you stranded if the remote fails. Locate the wheel-nut lock adapter if the car has locking wheel bolts, because replacing that single part is troublesome. Where the car uses a keypad, phone app or a security code stored in the handbook, confirm you have actually received it. If you have any doubt about who else may still hold a key, consider having the locks or key codes reset.
Settle the faults found at the pre purchase inspection
If you commissioned a pre purchase inspection, its report is your action list for the first week, not a document to file away. Read it again with the car in your possession and separate the findings into what needs immediate attention and what can be planned. Items flagged as advisory, such as tyres near the wear limit or a slightly weeping seal, can be scheduled, while anything safety-related should be addressed before you rely on the car daily. Acting now, while the seller's account and the inspection are both recent, keeps any negotiation or follow-up grounded in documented fact.
Where the inspection revealed faults that were reflected in the price, make sure the money you saved is actually set aside for the work rather than absorbed elsewhere. Get quotes promptly, because parts availability and workshop schedules can stretch a simple job into weeks. If a finding turns out to be worse than described once a workshop investigates, your inspection report and photographs give you a clear record of the car's condition at purchase. Closing these items early converts the inspection from a one-off check into a maintained, known baseline that you control from the very first week onward.
Prioritising safety-critical repairs first
Deal with brakes, steering, tyres, lights and any suspension play before lower-priority cosmetic or convenience items. A car can drive and feel normal while carrying a fault that only matters under hard braking or in an emergency manoeuvre, which is exactly when it counts most. If the inspection noted uneven tyre wear, a soft brake pedal or a knock over bumps, book those first. Use the report's severity notes to order the work so that the car is fully dependable before you extend your daily mileage or take longer trips.
Turning inspection findings into a repair plan
Group the remaining findings into a short plan with rough costs and timing, so nothing drifts unaddressed. Some items pair naturally with the first service, saving labour, such as replacing a worn drop link while suspension work is already underway. Others can wait for the next interval if they are stable. Share the inspection report with your chosen workshop so they understand what was already known and can confirm whether anything has changed. A written plan keeps the follow-up disciplined and stops small advisories from quietly becoming larger repairs later.
Register the details and set your maintenance baseline
With the mechanical and legal essentials handled, record the details that make ownership smoother from here. Note the registration date, the insurance renewal, the next roadworthiness test due date and your new service baseline in one place. In Hungary the periodic technical inspection has a set validity, so check when the current one expires and diarise it rather than waiting for a reminder that may still go to the previous owner. Update the registered address if you have moved, and confirm that any motorway vignette arrangements are in your name for the routes you actually drive.
This is also the time to gather the car's documentation into a single record you can maintain. Keep the sale contract, the service history you received, your new service invoice, the inspection report and the insurance policy together, digitally and on paper. Store the location of the locking wheel-bolt key, the spare wheel or repair kit, and any radio or security codes. A tidy record protects the car's future value and makes the next roadworthiness test, service or eventual sale far simpler. It also means that if anything covered by remaining warranty fails, you can prove the servicing history immediately.
How an on-site inspection in Budapest shapes your first week
An independent on-site inspection in Budapest shapes the whole of your first week, because it hands you a specific list of what to check, service and settle rather than a vague sense that the car seemed fine. When the inspector examined the car before purchase, the fluids, tyres, brakes, locks and any advisories were all noted, so your early service and repairs can target real findings instead of guesswork. Having that report written in English removes the language barrier that often makes the post-purchase week stressful for expat buyers dealing with Hungarian workshops and document offices.
The inspection also protects you if the first week uncovers something. Because the car's condition was documented and photographed at the point of sale, you have a clear reference if a workshop finds a fault that was hidden or misdescribed, which supports any conversation with the seller. For a buyer following this checklist, the on-site inspection is what turns each step from a general precaution into a targeted action: you know which fluids lack proof, whether a second key is missing, and exactly which advisories to close. That is how a pre purchase check keeps paying off well after the car is bought.

Frequently asked questions
How long do I have to transfer ownership after buying a used car in Hungary?
As the buyer you must register the change of keeper within fifteen days of the date on the sale contract. The seller separately reports the sale to the authorities, usually promptly after handover. Missing the deadline can lead to fines and can leave road tax or traffic offences recorded against the wrong person. Bring the signed contract, your identification, the vehicle documents and proof of valid insurance to the government office to complete the transfer.
Should I change the oil right after buying a used car?
Yes, unless the seller provided dated proof of a very recent oil and filter change, it is sensible to change the engine oil early in the first week. Old oil of unknown age and mileage is an inexpensive risk to remove and it protects the engine you have just bought. Changing it also gives you a verified service baseline from which all future intervals are measured. While the car is on the ramp, have the brake fluid, coolant and gearbox oil checked as well.
What should I do if I only received one key with the car?
Test the single key on every function first, then order a spare early rather than waiting until it is lost. A replacement coded key and its programming can be costly, especially on newer cars, so it is better to plan for it than to be caught without a backup. If you have any doubt about who else may still hold a key, ask the seller how many were issued and consider having the codes reset. Keep the spare in a safe, separate location once you have it.
How do I handle faults that were found during the pre purchase inspection?
Use the inspection report as your first-week action list, separating safety-critical items from advisories that can be scheduled. Address brakes, steering, tyres and suspension issues before you rely on the car daily, and get quotes promptly so parts and workshop time do not delay the work. If a finding was reflected in the price you paid, set that saving aside for the repair rather than spending it elsewhere. Keep the report and photographs, as they document the car's condition at purchase if anything proves worse than described.
What paperwork should I keep after buying a used car?
Keep the signed sale contract, the vehicle registration certificate, the service history you received, your new service invoice, the inspection report and the insurance policy together in one place. Store any security codes, the locking wheel-bolt key location and the whereabouts of the spare wheel or repair kit with these records. Good documentation makes the next periodic technical inspection, service or resale far simpler and supports any warranty claim. Keeping both digital and paper copies protects you if an original is ever lost.
