I'm still undecided to be honest, my ten year is not due till march, and I'm only on 78k, so got a few months to think about it, part of me wants to keep Lexus stamps, but the other part wants to save money, knowing that I plan to keep this car for a good few years yet (unless my lotto numbers come up) I'm swaying towards having it done by a local garage, as when I come to sell it on it will be 12 + years old, and seeing the price they go for now, and with a next gen IS out soon, the price (sadly) will only go one way!
