A mag i just bought actually had a writeup on them. Basically they're very easy to drive fast bu in terms of feedback and driver involvement, they're not particularly rewarding. This is offset (depending on your view) by the technology they come with. Very advanced for their time, like the GT-R. Overall its a quick GT car, not a sports car.
This last but is entirely rumour, but i remember hearing that modding them is not as straightforward as other cars. The turbos are pretty pissweak but due to location a str8 swap is difficult.
