snowkatt: that is not hard to do

ThePunishedSnake: Sorry, but this is a totally different thing. You actually USE your car, right? So it degrades during time, and after a while, you need to change it because repair it often and often in the end will cost you more money then buying a new one.

Also improving a vehicle is different, because technology evolves and a tmodernFocus will consume much less instead of a ten years old Focus. No one want to buy a ten years old machine. It's not an "artistic" product with a value despite of its age like a videogame could be. A ten years old Focus is only a worst product.
