Good friend and pro challenge driver had a '97 ACR that I drove in a couple of pro solos and locally. It was a decent autocross car at the time, but I never could warm up to it. Lots of grip, but very bland. I used to joke that if I had started in that car, I would have taken up knitting instead. Of course most of that is that I absolutely hate FWD.
Even then though it spent a LOT of time in the shop and had a ton of stuff replaced under warranty.
Another friend road raced one in showroom stock and lost more than one engine in a season. He ended up renting one wherever he went to use as a source of spare parts!
still, they are quick autocross cars, and most of us still hate to get beat by one!
