Thanks for the info guys, I really appreciate it. I'll probably shop around for the parts myself, and see if I can save a little money...On the upside, I LOVE the car! Got a good deal on it (other than this issue). One owner, 89k miles, new tires (20", as you know) clean carfax, maintained with extended warranty up to 72k miles through BMW. Very clean. Doesn't look like anyone's every sat in the back seats...Got it for $17k! The indy shop looked it over and only found a couple of small issues (other than this issue).
