sure ya can, you can use any car that has 4wd on the dirt track, (so far that i know?) i like using the rally cars though, as they are closer to the performance of the car im racing.. its not just an easy 3-7 laps, blowing away the competition in the escudo.. but if you cant beat them, try a subaru Impreza 22-b, or one of the RUF's..
