I agree with Scaff.
The '05 is an update of the GT40. A no-frills car that is heavy for it's class, and has a high center-of-gravity. No driving aids of any kind, and it inherited a body with aerodynamic issues. The engine sound is wimpy, I have to keep an eye on my speedo. For all of that, it's a blast. I also discovered that if you put a brakes-controller on the '05 set rather low, don't need racing brakes, the high-speed pull goes away, but I still have to brake earlier than others. The rl car has anti-lock brakes...

These settings are with a GT Force wheel/pedals, active steering is 'off', the cars feel pretty good. The line between Yahoo! and @^%$! is not very wide.
I originally thought that it should have been a better car, but found that the car needed a better driver. Ford says: "Nothing between you and the road."(except anti-lock brakes)
