Agoda for Thai Car Auctions

Know first,
profit first.

SianSmart helps you know before others which cars are worth bidding on. Every auction house grades differently — letters, stars, inspector opinions. None of it is comparable. Most dealers add ฿30,000+ "fear buffers" to every bid. SianSmart reads every inspection sheet and photo with AI and translates it into one score you can compare.

Why dealers overbuffer

Auction data from different houses isn't comparable. Without a tool to read it, dealers pad every bid with a large repair buffer.

🏦

Banks liquidate

Repossessed vehicles flood the market every week

📋

SIA & AUCT upload raw data

Every auction uses a different grading system — letters, stars, inspector opinions. None of it is comparable.

→
😰

Dealers pad every bid

No comparable data — so they add a large repair buffer to every bid

Result: margin lost to guesswork

Dealers who see condition clearly bid more accurately — and keep more margin.

The Vehicle Report Card

Every auction grades differently. We translate it all into one transparent score — the system Thai dealers already know from school.
