In the UK, second hand BMW's are worth next to nothing because they have become a victim of their own success and the world and his wife owns one, thus reducing their premium status and therefore their value. How many G-K regs 3 series do you see on the road driven by someone who clearly would be a lot better off driver something slightly more affordable? Exactly. This is why only a mug would buy a 3 series BMW. Saying that though the new 5 series is nice, and so is the Z4, though for the money you'd be better off with a Lotus Elise, a proper sports car rather than a hairdressers one.
