How about a catagory for daily commuter car & have other cars for weekend fun? IMO more horsepower the better and to get 500+HP in Z cost too much. However, the Z makes a great commute car if you have winding roads on your commute route.
BTW- I'm on my seventh Z car... I love these cars ... Enjoy the ride !!!
If I was stuck with one car and carrying or towing wasn't an issue ... It would have to be the Z for sure.
