I found a guy with a 2000 M5 that is thinking about selling it. It has 135k miles, new tires, new brakes, Dinan intake, Dinan exhaust, Spec Stage III Cluth, and some brand aluminum flywheel. It has a rebuilt tranny as of 125k, and that is when the cluth and flywheel went in. No engine light, everything worked fine, except a few of the lines were out on the digital display. It's Black on Black, and the paint is in really good shape. He also updated the headlights to the 2001+ M5 lights. He said he'd take 22k for it. Any thought?
