Lexus CPO suv, clean carfax, but has an auction record with stru

本地BENZdealer卖Lexus GX460. 拿到carfax, 2 owners, first is a lease, second owned it for several years then traded it in to Benz. All serive records shown on carfax were done in a local lexus dealer.

carfax shows 本地 lexus dealer 从拍卖买来的，不久就卖出 as CPO. 没有别的记载。

我又在 autocheck.com to double check it. It shows 1 record of frame or structure damage.

打电话给本地 lexus dealer 问他们是怎么个CPO standard. 非常不耐心，说他们只用carfax. 

我本来以为Lexus CPO 是品质保证，现在看来也不能全信。 carfax 信息也不全。
