Two weeks ago my husband purchased a car from a guy. Everything seemed to check out fine. Yesterday we took it to the mechanic for some brake service and found out the the catalytic converter had been taken off. The guy we bought it from had an indiana title, I don't know if they do vet testing, but we are from GA and we have vet testing. It won't pass the VET unless this is replaced. Also after running a carfax report have found out that it has odometer rollback, which the guy knew about (on the carfax it was reported when he registered it) and failed to notify us about it. We are wondering what we can do in this bad situation? Just chalk it up as a loss?
