All that torque, even at 550 hp or so. I tried it a few times and it doesn't work for me either. I would need to spend much time to overcome the changes necessary to drive it well. In GT5 the Toyota 88 was the car that just seemed to work for me along withe the RM 69 Camaro and the Corvette race cars.
GT6 has changed things a bit so it's like a new game now trying to find the car that "just works" for my driving habits. So far I have one I can think of that I can win with in it's class, the Audi rally car that's in the 15th anniversary collection. I not only can win, I relax more doing it. It gives me notice of what it's doing. Doesn't swap ends without warning and when it starts to get loose a simple correction is all that's needed. Some cars just won't let me correct when they start to let loose.
