No one can question that the Z3 is an awesome driving machine - pure fun to drive. My problem is that the car spends a lot of time being towed to the dealer for repairs. Three times the throttle assembly has failed, requiring a tow and average of about one week to fix. And now it appears it has happened again. Lemon-law? Tried that - but the problem started after 20K which is beyond lemon-law consideration. In short: BMW has not responded in a professional manor, and this is the worst car experience of my life. No more Beemers for me.
