I did the Audi Driving Experience and it was great. I went from a loaded 2011 S4 to the M3 and I love both vehicles. The R8 in V10 form is a beast and I rode as a passenger on a hot lap with a professional driver in the R8 V10 plus. It was amazing! I can't imagine many vehicles that could be more fun to be in aside from other exotics. Ahhh, that V10!
