The seller usually warrants that, at handover, the car didn't have a defect cutting its value or its use. If you already knew when you signed, that warranty gets thinner. Ordinary wear after you drive it away is a different thing. An ad that says no accident and no flood has to sit next to what's written on the handover sheet.
Repair records, fault codes, and the dates you went in are the evidence. Don't modify it while you're angry, and don't throw the old parts out. Cutting the price and cancelling the sale are two different moves. The period is whatever the Civil Code says. I'm not counting your last day. You saw the car at the shop. Don't assume the seven-day cooling-off from mail order.
What you can do first
- 01Put the order form, the ad, and the handover photos in one folder for that day.
- 02Keep every shop order. Write what the fault was.
- 03Don't sign the balance, or a slip that says you already knew the condition.

Rewritten in my own words. Not a judgment and not a law firm's article. If a number shows up, it belonged to that public discussion, not to you. Check the Judicial Yuan judgment system. These started as public discussions of car crashes. I rewrote them here. Not a law firm's article.
I'm not a lawyer, and I'm not a mediator. I can't decide this for you. The statute that counts is the one still in force. Judgments live on the Judicial Yuan site.
