Yours in one of the cleaner ones I've seen in a very long time. Mine in just a daily. nothing special- just stock. Wheels are from a 91 318is I owned and couldn't part with them because I spent lots to get them refinished. So I thought it would look good on the black car. I had a peek inside too. I worked for Beach auto back in its day when it was around before getting finally torn down.
how long have you owned the M?
