Such a waste.. I guess if it's purely hobby, cool i guess. But if you really want speed you are so much better off just buying a platform that was made for it, rather than driving around in a Frankenstein car. (Which was really nice in the first place). In my opinion it is just spending a lot of money and ruining the car.
