I will be looking at a 2001 550 with supposedly factory modular wheels. The owner does not have the original window sticker showing the options on the car. He says they are original from the factory. How can I confirm this? Were they made by Speedline or BBS? Are they the same wheel as the 575 but in 18inches? Thanks much Gary
Give the full chassis number to FMNA and they should be able to tell you what wheels the car was originally imported with.
