My G60 now has nearly 180k on the clock. Its nearly all motorway miles, but even so someone mentioned to me about getting it rebuilt, or stripping it down and giving it a good going over. What would be involved in doing this? Im a fairly competant DIY mechanic so would definatly attept this myself. What sort of things would need doing? Is it just a case of strip her down and clean her up, or should major components be replaced, and if so whats likley? Finally, a long shot, but how much would this likely cost me if its the replace parts option?
