Ok pure personal preference and driving style. Sure you can say mines lancer and nothing is wrong with that. However I would say SVT Cobra and you can't compare. Two entirely different cars with 2 entirely different drivers.
Yah, Ford GT40 is good for drifting and gripping, I can drift with him, and do grip with him, it is good with the both (drift and grip). It is a great car.
About the SVT Cobra, could it be a Ford Mustang? (I am portuguese, in Portugal doesn't exist Ford Mustang) I never tried a Ford Mustang in Gran tursimo 2, but it seems be very famous in this forum, I have to test this car.
