BMW 8 Series Pre-Purchase Inspection in Budapest
For buyers who cannot tell a healthy BMW 8 Series from a well-disguised one, we provide the technical judgement — on site and in writing.

Worth knowing about the BMW 8 Series: it covers the 6 engine and drivetrain versions we list, while it spans engine sizes of 2993–4395 cm³.
Our inspector arrives prepared for this exact BMW 8 Series, knowing its weak spots before the bonnet is even opened.
If auto inspection or independent onsite auto inspection service is on your mind before buying the BMW 8 Series, our on-site, English-language inspection is built for precisely that.
Why a pre-purchase inspection matters for the BMW 8 Series
Knowledge is leverage. A buyer who can point to measured paint readings and a clean — or not so clean — diagnostic scan is in a far stronger position at the negotiating table.
You would not buy a flat without a survey — a BMW 8 Series costs enough to deserve the same scrutiny.

What we focus on with the petrol BMW 8 Series
- Carbon build-up. Direct-injection petrol engines are prone to intake carbon; we look for rough idle, misfires and the symptoms that come with it.
- Oil consumption. We check oil level and condition and ask the right questions about top-ups, since heavy consumption points to worn rings or seals.
- Cold-start behaviour. A genuine cold start reveals knocks, smoke and rough running that a warmed-up engine hides.
- Cooling system. Water pump, thermostat and coolant condition are inspected for leaks and overheating risk.
- Turbocharger health. On turbo engines we watch boost behaviour, smoke on load and any whine or shaft play that hints at a tiring turbo.

BMW 8 Series: frequently asked questions
How much does a pre-purchase inspection of the BMW 8 Series cost?
An on-site inspection of the BMW 8 Series starts at 35,999 Ft for the Standard package, where you attend in person and we go through the findings with you at the car. The Digital Inspection Package costs 39,999 Ft and is carried out without you there, with the results sent as photographs, video and a written report by email. The inspection itself is identical in both, the call-out fee within Budapest is included, and there are no hidden extras.
What hidden problems can a used BMW 8 Series have?
There are a few things that tend to need attention on a used BMW 8 Series. When we inspect one, the points that most often need attention are carbon build-up, oil consumption and cold-start behaviour. Catch them early with a proper inspection and the BMW 8 Series can be an excellent purchase — this is the heart of what people want from auto inspection and independent onsite auto inspection service.
How long does an inspection of the BMW 8 Series take?
A typical BMW 8 Series inspection takes roughly one to one-and-a-half hours at the car, though a complex or high-mileage example can take longer. We work to a fixed checklist of more than 500 points and never hurry a car along to reach the next appointment. In most cases you will have the verdict the same day.
Do you read the fault codes on the BMW 8 Series?
Yes — a full on-board diagnostic scan is part of every inspection. On the BMW 8 Series we capture both live and stored fault codes, including ones a seller may have cleared shortly before your viewing, and we read live data to catch systems that are struggling before any warning light appears. On electric and hybrid versions this also opens up the battery and charging data.
Do you come to wherever the BMW 8 Series is parked?
Yes — this is a fully mobile, on-site service. An English-speaking inspector travels to the BMW 8 Series whether it sits on a private driveway, a dealer forecourt or a side street, anywhere in Budapest and the towns around it. You never have to drive an unfamiliar car across the city to a workshop just to have it looked at.
Can you tell whether the BMW 8 Series has been in an accident?
We measure paint thickness across every panel and examine the structural areas, seams and fasteners for filler, resprays and signs of straightening or fresh welding. Together these reveal the great majority of accident repairs that a casual viewing would never expose on a BMW 8 Series. Where a reading raises a question, we investigate further before drawing any conclusion.
People search for auto inspection — is that what you do for the BMW 8 Series?
Yes. Auto inspection is simply another way of describing what we do for the BMW 8 Series: an independent, on-site inspection before you buy. Our inspector comes to the car, works through the full checklist and the diagnostics, and explains every finding in English. Plenty of buyers also look for auto evaluation, and that is the very same service.
Do you offer independent onsite auto inspection service when buying the BMW 8 Series?
We do. For the BMW 8 Series, independent onsite auto inspection service means a complete, on-the-spot pre-purchase inspection carried out wherever the car is parked in Budapest, with the result reported in English. It is the same thorough check buyers have in mind when they search for pre purchase car health check mobile — independent, documented and yours to act on.
