I would like cars similar to:
1st gen 1.8L Miata (no surprise, that's what I autoX)
aftermarket turbo version of the Miata (AKA Flyin' Miata II system, 270-280 HP miata)
Corvette 02-04 Z06
2nd gen MR2 and MR2 turbo
AC Cobra
F360 (high reving, mid-engine V8, play mate for the the FZ50).
Yeah, the NA Miata and MR2 would blow away the XR GT and XFG, the turbo version of these would destroy the TBOs, and the Vette would kill everything but the GTRs, but it would be really fun.
