I think either the '03s or '04s had very nice 19" V-spoke rims or something with the sport package. The earlier ones just had the boring (IMO) rims like the SP 750li rims you see now. And they look very nice when chromed too.....

Like others have said, stay away from the '02s......lots of problems there. Or consider a 2001 740i sport.......my personal choice.
