I had bought a car on 10-27-09 and when after the 2 and a half months I waited I got the reg ant title in mail on the reg it said I bought the car on 12-7-09 he had changed the dates on the pink slip copy I had gotten because he sent it to dmv after his 20 days were up.. when I had bought the car I didn't sign title didn't even see one... and I don't believe that he even had a title at time of sale can a dealer do this??
