If it's been wrecked they have to disclose it on a new car I'm pretty sure. If she bought it used not so much.
Backstory: my parents bought a 02 Impala brand new from Reed lallier Chevy on a Saturday night didn't get out of there until after 10pm. Came home, the detail shop was closed so dad was to bring it back Monday. Sunday morning my brother in law says " hey the Impala badge is missing on the passenger side". The one on the c pillar. We start looking and the paint is obviously orange peeled on that whole side of the car. I investigate further and the paint is chipped off the door hinge bolts like a wrench or socket has been on them.
Dad goes back Monday before opening but parks infront of show room. When sales manager gets there dad says " We bought this car saturday night, I think this cars been wrecked". SM goes "oh hell yeah, that car got tboned so hard on the passenger doors on a test drive we had to replace both of them and the fender.". Dad goes "well no one told us"
SM said they should have, we're selling it as a used car. Where was it on the lot? Dad said right there in that empty space (front and center by the main showroom entrance, surrounded by brand new Impalas)
SM went into full ass kiss mode, tore up paperwork in front of dad and got him another car off another dealer with basically the same options for the same deal.
