回複：建議牛兄看一下加州的相關資料 (這是OAG的官方資料)

I am still confused.

'As a result, there is important coverage for motorcycles, the living quarters of a mobile home, used vehicles sold with a dealer's express written warranty'


But in this specific case, the seller is a non-dealer, neither did she did provide 'express written warranty'.

So the seller is not responsible, am I right?
