If GT4 allows online trading of vehicles then it would be even more important for cars that are tuned to hold their original purchase price and then have it go up by certain percentage points. If milage returns, then perhaps after say 1,000 game miles the value starts to decline. I hope that in some future version of GT that most if not all car purchase will be online, and when players sale their cars they go into some sort of online car lot. Imagine browsing thru the car lots and maybe having the option of choosing for example shoping for a 69 corvette, and there might be say 100 in the lot, all with differnt user paint jobs and other modifications. It would just add alot more depth to the game finding the best cars. Perhaps also in a future version of GT4 their could even maybe be online car shows, heck maybe even in GT4 with the photo mode. Players upload photos and then players vote on the best. Top winners get a certain amount of credits or other prizes.
