The "Fear Buffer" problem

Thai dealers systematically underbid — not because cars aren't worth more, but because auction data gives them no way to assess risk.

🏦

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 bid blind

Add a large "fear buffer" to every bid to cover hidden risks

Result: Everyone loses money

Sellers get less. Buyers miss gems. The market is permanently mispriced — until now.

The Vehicle Report Card

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

We read the fine print.
So you don't have to.

Automatic flags for the risks that cost dealers the most.

🛑 Hard Knockouts — Skip
  • Serious damage detected
  • Legal or document issues
  • Structural problems
⚠️ Soft Warnings — Price down
  • Financial liabilities
  • Cosmetic condition issues
  • Above-average wear for age

The "fear buffer" is dead.
Stop overbidding on safe cars. Stop underbidding on hidden gems.
