i had a 99 z3 m coupe with most all dinan mods including supercharged. i also installed a euro six speed gearbox. i did not care for the roadsters but really like the "shoe" and especially the M model. seating is very tight and has very little rear adjustment due to the rear compartment. and, the steering wheel is not adjustable. the cars are relatively heavy...about 3100 pounds i believe. the radiator side tanks are plastic and can fail overtime as well as the plastic water pump impellers. some cars have had spot welds in the rear compartment break in and around the area of the single mounted rear differential. i installed a rear reinforcement kit in mine but saw no signs of welds being cracked or beoken. this kits included a second ear for the differential. i really enjoyed the car but sold it after three years. if it had been laguna seca blue i would probably still own it!
