The math
One overlooked defect costs more than ten reports.
Without a public price, the math doesn't work in percentages. But every classic buyer who has been stung once knows the orders of magnitude. These are the four categories where real money is lost on classic cars:
Substance & body
four- to five-figure
Hidden rust in sills, wheel arches, floor pans. Often freshly painted in the photos — filler beneath.
Drivetrain & suspension
four- to five-figure
Gearbox, differential, clutch, axle damage. One single fault eats ten reports.
Provenance & originality
value-defining
Non-matching engine/gearbox numbers, repainted accident damage, patchy history — halve the resale value.
Reversing a cross-border sale
four-figure + months
Transport, lawyers, lost holiday. On a private sale without warranty, practically never successful.
Just one of these findings — and €399 is the cheapest money you'll spend on this purchase.

Specific to this vehicle
What typically goes wrong on a 2007 | Porsche 911 Carrera 4 (997.1)
Every car looks good in photos. These are the weak spots we inspect with extra care on this exact model:
02
Drivetrain: chain, DSG, turbo, DPF
Timing-chain stretch, DSG mechatronics, turbo bearing failures, clogged particulate filters: the classic five-figure repairs of this generation. We check chain noise, shift behaviour and boost pressure.
03
Body, paint & accident history
Repainted accident damage and swapped panels become visible with a paint thickness gauge and a trained eye. We measure every relevant panel and document deviations.
04
Service book, previous owners & recalls
A complete manufacturer history, documented previous owners and completed recalls all shape the value on modern classics. We verify the paperwork and cross-check it against manufacturer data.
Standardized protocol
112 or more checkpoints. 40+ images on average. 15 mandatory.
Every CT inspection follows the same protocol — guided by our purpose-built inspector app. Depending on body style, the expert is walked through 112 or more checkpoints and shoots 15 mandatory photos from pre-defined angles. Including detail shots, that produces 40+ images on average per report. On certain models additional checks are added automatically — e.g. the soft top on a convertible. The consequence for you: the report has the same depth every time and is comparable 1:1 with any other classic on Classic Trader.

FAQ
What buyers ask before booking
Who actually inspects my vehicle?+
One of 200+ classic-car specialists in our network — matched to your exact marque, era and the seller's location. Each inspector is vetted by Classic Trader and independent of the seller.
How many checkpoints are there?+
A standardized protocol across 14+ assembly groups: engine bay, engine, body, wheels & tires, trunk, interior, electrics/electronics, cooling system, brakes, underbody, transmission, steering, chassis and — where possible — a road test. The exact number depends on body style: convertibles add checks for the soft top, hardtop cars get their own block. In total, there are 112 or more checkpoints. The report includes 15 mandatory photos from pre-defined angles plus additional detail shots — 40+ images on average per inspection. Our inspector app enforces every mandatory photo.
What if the seller refuses the inspection?+
Full refund, immediately. In 95%+ of cases serious sellers welcome an inspection.
How long from booking to report?+
Appointment within 5–7 working days. Report 24–48 h after the on-site inspection.
Are you really independent of the seller?+
Yes. Classic-Trader doesn't broker vehicles, we don't get commission. Our inspector is paid by you, not on outcome.
What if the vehicle has already been sold?+
Full refund. We verify the listing is still active before booking.
Are there hidden costs?+
No. €399 flat, including travel within Germany, including report, including translation.
What's in the report?+
Overall grade, identity check (VIN, engine & gearbox numbers), body & paint incl. paint thickness measurement and damage diagram, underbody & rust, engine & drivetrain, suspension & brakes, electrics, interior, road test, history & paperwork, expert verdict with market context, unique report ID, and an extensive standardized photo gallery. Typically 25–40 pages — depending on the model, the findings and additional detail shots.
Is the car put on a lift?+
Whenever the seller and the venue provide a lift, we inspect the underbody on the lift — that's always the goal. If that's not possible (private sale in a garage, no workshop on site), we work with trolley jacks and an endoscope camera underneath. We transparently document what was checked and under what conditions.
Make this decision with data, not gut feeling.
