If you own a Nissan GT-R and bring it to Japan, it's capped at a top speed of 111mph. Using GPS, the car knows if you're at a racetrack, and then the speed limiter is bumped (or removed, I forget).
Also, if you "own" a Ferrari FXX you truly have no say over it. You're essentially paying to drive it. Ferrari holds onto the car for you and you can only drive it at approved race tracks.
