By now, the Ford GT is somewhere around 10 years old. It is somewhat eclipse by a newer 2nd generation Ford GT (which looks equally impressive) but for some odd reason, the original GT has been keeping its value, often selling for much more than it was bought for. That's normal for exotics I guess, but not really normal for Ford vehicles in general.
It's amazing to me though that behind all that power and beauty lies the same knobs and levers as a Ford Focus of that time. I guess that's why people don't expect Ford vehicles to rise in value after leaving the lot.
