Hi Bapesta, and welcome to the forum!
I called inquiring about the same car you did, about 4 months ago - it's at BMW NW in Fife, right?
My advice to you is DO NOT
buy that car; the owner - whom I spoke to - is a pompous jerk, and not worth your time or money. Granted, I can't afford the car - new or used - and he may have picked up on that. However, I would still say that since the car is past break-in, and you don't know how he used it, I would spend the extra money and buy new.
I look forward to seeing you at future meets! I am the unofficial, official photographer for them
