hey all new to the group. I just recently brought a 1980 Chevy 2 door coupe Malibu from a guy down in the maryland area, title for the car matched the vin number on the car but when i try and decode the vin number it came back as ............ do you guys think he changed the vin from a el camino and put on this malibu? I'm really confused, not sure what to do.
