You did not tell us anything about the car to identify it. So many questions, what make, model, engine, transmission, mileage, price, the warranty on the vehicle. CarFax, AutoCheck, NMVTIS Report, or a NICB Report? Did you get at pre-inspection from other that CarMax (I actually do not know if they allow this…). Were all (if any…) recalls performed on this vehicle (NHTSA Vin Report)? So many questions…
I am also guessing that you did not get the limited extended warranty offered by the actually dealer nor the more inclusive, long term, CarMax Policy, is that correct?
