Bought a 99 suburban from EMP&GMC in 2002 Carfax checked out fine then a couple years later bondo on both rear quarters came off.Carfax is worthless, honestly. I've known several people whose vehicles had been badly wrecked and Carfax didn't report it. It's required by some dealers or whathaveyou, but I don't put a damn lick of faith in it.
Been crunched by jack-knifing a trailer into the quarters. Carfax worthless.
