I get this problem too sometimes.
or the car won't appear at all, or the game will crash upon loading.
Its probly becuase the car itself is screwed. which in this case means the car should be removed from the host site. but they can't always be on the ball if the mods their hosting work.
I don't use vccm or whatever its called but if you did uninstall the car mod but your still having errors maby its becuase the other installs were'nt put back to normal like the handling.cfg
deafault.ide and carcols.dat .
