What's hiding inside that auction car?

"Good eye wins, bad eye loses" — Thai dealers face these risks every week.

Resprayed fender panel — visible paint mismatch
🚨

Repainted damage

Fresh paint hiding collision damage. Looks great outside, structural nightmare inside.

Odometer shows 80,000 km — wear says 200,000+
🚨

Rolled odometer

Shows 80,000 km but real condition says 200,000+. Wear beyond what numbers claim.

Engine oil leak at valve cover — hidden damage
💀

Hidden repair costs

Bought for 350,000. Actual repairs: 150,000. Your entire margin — gone.

⛔ Result: Bought it — now you're stuck

Most dealers who lose money at auctions didn't bid wrong — they just couldn't see the problems before bidding.

See everything they're hiding.

Every inspection report from SIA/AUCT, read by AI — one score, comparable, nothing hidden.

Overpaying isn't bad luck — it's bad information.

We read every line of the report. You just check the signal.

🛑 Walk away — don't touch
  • Severe collision damage or structural failure found
  • Suspected odometer rollback — condition doesn't match numbers
  • Document issues — Blue Book doesn't match
⚠️ Worth it — but negotiate down
  • Outstanding finance — must clear before transfer
  • Partial respray — may hide cosmetic damage
  • Wear beyond age — repair costs may be higher than expected

Worth it? Check before you bid — no more guessing.

The hammer price isn't the real price.

Most dealers who lose money forget the hidden costs after the bid.
