Hi, friend of mine is seriously looking at a is200, i believe it's a 2002 and got about 80k miles.. previous owner has said it uses about a litre of oil per 1000 miles, not that this should be considered normal, but is it a concern on these engines? I know some engines are prone to using oil and it's not really an issue just keep an eye on it, others it's a good indication of problems. Cheers Chris
