Dom, If you go and look at it I would advise looking through a manual real quick to make sure you know how to operate all the widgets. If anything doesnt work right you can use that as negotiation. Push the check system button on the gauges, look for when the last time it was serviced by BMW, the more green squares the better. Check for weights on each wheel alot of them may mean one is bent, these 20's i think would bend pretty easy. Check for both keys, manuals, etc. Good luck looks nice!
