Yes it was fun, about 2 hours of thrashing all these cars in the morning (IS350, 335, C350 3.5Ldirect-injected, A4-2.0T, GS350, LS460). Lots burning rubber, and smoking brakes on 3 autocross courses.
My favorites to drive were the IS350 and 335. For ownership I'd consider IS350 or C350 which should be the most reliable of the group.
