I got a chance to test drive the new Mazda RX8 before going on vacation last week. I was interested in the car initially because it was basically a sports car with 4doors. Im glad I got my IS300!!! First I would like to say it is a nice car, however despite all the hoopla about it being a lighter more tossable car, my IS300 felt just as fun to drive. I also didn't feel the Hp difference. Maybe it's because of the lack of tork. My wife drove the car too, and she is no lead foot, she said she felt no big difference. The car does sit lower and looks some what unique, but after driving for a few minutes the car felt less of a car than my IS300. Call me spolied, but it would be hard to step down from a lux division despite the IS300 short comings. Again nice car, but not enough for me to get rid of my IS300. If I had to,only for the 350z or the G35 coupe.
