Loads, because the cars I drive regularly are at least 400HP. I spend most of my time driving either the Pennzoil Nismo, Viper GTSR (Oreca and Concept), Lotus Motorsport Elise, Gillet, Toyota GT-ONE and a few other high-powered cars.
The only car I have 0.0 miles on for a reason is the Viper GTSR Concept I won for all-golds on the S-license. The one I use I got from somwhere else.
