Pre-Purchase Inspection for the Porsche 911
Thinking of buying a used Porsche 911? We come to the car, anywhere in Budapest, and check it from end to end before you hand over a single forint.

The Porsche 911 produces 350–700 hp; it also covers the 15 engine and drivetrain versions we list, and the inspection accounts for both.
We bring the workshop to the Porsche 911: diagnostics, a paint gauge and a trained eye, all at the seller's location.
Considering car history check or onsite car diagnostic before purchase for a used Porsche 911? That is precisely the independent inspection we carry out at the car.
Why a pre-purchase inspection matters for the Porsche 911
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.
The seller's reassurance about the Porsche 911 is worth little next to a paint gauge and a diagnostic scan.

Petrol-specific checks on the Porsche 911
- Turbocharger health. On turbo engines we watch boost behaviour, smoke on load and any whine or shaft play that hints at a tiring turbo.
- Timing chain or belt. We listen for chain rattle on start-up and check belt service history, because a skipped interval here is one of the most expensive engine faults to put right.
- 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.
- 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.
- Cold-start behaviour. A genuine cold start reveals knocks, smoke and rough running that a warmed-up engine hides.

Porsche 911: frequently asked questions
How much does a pre-purchase inspection of the Porsche 911 cost?
An on-site inspection of the Porsche 911 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.
Which parts of the Porsche 911 deserve the closest look?
A used Porsche 911 is a sound choice with its eyes open, and that means knowing its weak points. Experience tells us to start with turbocharger health, timing chain or belt and oil consumption. None of these shows from the driver's seat, which is why buyers who search for onsite car diagnostic before purchase really need an on-site check — and our Porsche 911 inspection covers every one.
Will the inspector and the report on the Porsche 911 be in English?
Always, on both counts. Your inspector speaks fluent English and explains every finding in plain terms while you decide, and the written report on the Porsche 911 is produced in English. Each point is graded — sound, worth attention, or serious — so nothing is lost in translation when it matters most.
Do you read the fault codes on the Porsche 911?
Yes — a full on-board diagnostic scan is part of every inspection. On the Porsche 911 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.
Is your inspection of the Porsche 911 genuinely independent?
Completely. We work only for you, the buyer — we do not sell cars and we take nothing from the seller. Our report on the Porsche 911 reflects only what we actually find, whether that lets the sale go ahead with confidence or stops you walking into an expensive mistake.
Can you inspect the Porsche 911 if I cannot be there in person?
That is exactly what the Digital Inspection Package (39,999 Ft) is built for. We attend the Porsche 911 on your behalf, carry out the complete inspection, and send you a detailed report with clear photographs and short video clips by email. It is the natural choice if you are buying from abroad, live in another city, or simply cannot make the viewing in person.
People search for car history check — is that what you do for the Porsche 911?
Yes. Car history check is simply another way of describing what we do for the Porsche 911: 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 inspection Budapest, and that is the very same service.
Do you offer onsite car diagnostic before purchase when buying the Porsche 911?
We do. For the Porsche 911, onsite car diagnostic before purchase 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 expert pre purchase vehicle inspection Budapest — independent, documented and yours to act on.
