I thought about sneaking into my friend's Lexus at night and replacing the wheel with a Dual Shock 2 controller. It would be more interesting to be in a "RC car" sitting in the driver's seat than watching the car from afar. Force feedback is a must.
As for the Driving Force Pro, the wheel is too small to use comfortably in everyday driving. It would make more sense to get a MOMO wheel and put the shiny GT badge on it.
