hello,
nice car and nice driveway - if this driveway is private property you must have quite a nice house!
just looked up the prices for the "csl" wheels:
the real 19" 359M Y speiche (CSL, competition package, 1M) are € 541,--front and 603,--rear per piece
the price of € 4350,-- is for all four wheels plus michelin tires (michelin tires are awful expensive)
i dont think the wheels will fit the e82 without any bodywork - and i dont know of any 359Ms in 18"???
