Hey guys, I've noticed some people have multiple M3 GTRs in either their garage or my cars. When I play online, same racer brings different bmw cars with conflicting colors, vinyls and rims each time. How is this possible?

¤EDIT¤ All I want to do is to have all-stock M3 and customized one. (Btw I'm not confused with other gray colored bmw.)

Please help.
