Every once in a while you'll need a lightweight K car and the Honda Beat Z is a good one to have. The Ford RS200 for some rally events and the Evo Super Rally Car '03' or the Subaru Rally car '03' are good to have also.
@GTOracle, I suppose the only thing that we know for sure is that the Takata NSX was replaced by the Woodone Supra as the GT500 car of choice
