Structure Check
Structure only, engine not started
- Structure: major accident, flood, rollover, cut-and-weld
- Paint thickness around the car
- VIN and documents
- PDF checklist + photos on LINE
We check for major accidents, flood damage, rollovers, rolled-back mileage, engine, gearbox, electrics and documents, with expert advice and a guarantee* before you buy. Serving Bangkok, Nonthaburi, nearby provinces and all of Thailand.
A few thousand baht for an inspection tells you what you are buying, gives you room to negotiate, or lets you walk away.
Rebuilt structures affect both safety and resale value.
Electrical faults and rust appear later, even when the car looks fine today.
A low odometer reading means you pay more than the car is worth.
Fault codes cleared before the sale show up when we connect OBD.
We don't buy or sell cars and take no commission from dealers. The results are yours alone.
P3–P4 are inspected by Keng, with advice after the inspection. All vehicle types, including European cars and EVs.
P3–P4 guarantee the structure against major accident, flood, rollover and cut-and-weld damage. If we miss it, we buy the car back.
Every package includes a PDF report with photos, sent on LINE, so you can decide right away.
Real-time vehicle data analysed by AI, developed in-house by Scan2Car. Used in package P4.

No extra charges on site and clearly stated travel fees.
A used car has hundreds of points to check. We group them into 7 main systems and photograph every finding for your report, so you see it for yourself.
The core of every inspection. However good the repair, a major crash leaves traces.
Problems that don't show today but follow you for years.
We listen, look for leaks and feel how the car actually drives.
Modern cars fail electrically more often than mechanically.
Safety, and the costs that usually come right after you buy.
Make sure the car is the same one in the registration book.
The heart of an electric car and its most expensive part (P3–P4).
Modern cars have control units (ECUs) watching the engine, gearbox, brakes, airbags and electrics all the time. When something goes wrong, they store a fault code, even if no warning light is on yet.
The most common trick in the used car market is clearing codes before the sale. The warning light goes out and the car looks fine, but the problem is still there. An OBD2 scanner shows whether the system was recently reset.
| Looking only | With OBD2 |
|---|---|
| No warning light, so it must be fine | See the codes hidden in the control units |
| No idea if codes were just cleared | Know whether the system was reset before the sale |
| Engine sound at idle only | Real values while the engine runs (live data · P3–P4) |
| EV: only the battery % on the dashboard | Battery health (SOH) and every cell voltage (P3–P4) |
| Guessing from symptoms | Hard data and more accurate repair estimates |
OBD2 is included from package P2 · P3–P4 add live data during the test drive
A generic OBD2 scanner reads only basic data. For some brands we use dealer-level diagnostic software that reaches every control unit in the car.
Used in P3–P4 · e.g. Mercedes-Benz (XENTRY) and BMW (ISTA+) · Ask about other brands on LINE @scan2car

S2CDiag is software Scan2Car built from years of collected data and a real understanding of how cars work. It applies in-depth AI analysis to assess the engine, gearbox and electrics, to find faults today and those coming in the future.
All the data is compared with how a healthy car behaves, to find early signs of wear before symptoms appear. You know before you buy whether the car is truly sound or about to cost you money.
Results come as a score out of 100 and an S / A / B / C / D grade for every system. Easy for anyone to read.

“Really impressed with Keng's inspection. Straightforward and honest about what he found. Contacting him was the right decision, and I'll definitely use the service again.”
“Excellent. He checked every system, tested the suspension, explained things I didn't know, and advised on whether the price fitted the car's condition. Worth every baht for the confidence of buying a used car.”
