yeah, what mortal said should do the job, put the in-game graphics to high (I think it's under advanced->car geometry). I believe he meant that this thing is already mentioned in the FAQ, but if you have questions in the future, do check that out first
I have got the same problem Boniaski, I did put the in-game graphics to high and tested it and still all the cars are white so it must be something else.
just for info: i had the same problem with the decrypted gp4.exe (texture problems in high res) downloaded from gp4db (same as the officially posted Decrypted Nocd for GP4 1.02 by FairLight ). i tried my older decrypted gp4.exe (sightly smaller than the gp4db one, i think it's not the updated one) which does not produce this error and what i still use. if i change back to the fairlight exe the problem occurs again. so in my opinion this problem is to some extent the problem of this modified/updated gp4.exe.
