Make it more stock (no suspension tuning) and a bit more realistic (comfort medium max - no fantasy track tires on street cars!) and I'm there.
No power ---> more fun with less grip, some skill required even if it doesn't have 500 BHP.
I like 'regular' MX-5s, 120 - 160 BHP, not tuned like it's the Fast and the Ridiculous, like so many boy racer GT fans tend to do. Cars that you could, in theory, just hop into when putting your PS3 controller down,... unlike yer fantasy Ferrari. In other words, something that relates to real life driving.
