I've had my MS3 for about 1500 miles now...love it....but was bothered by an ocassional thumping/clanking come from the back end. At first I though it was a loose jack but after crawling around under the car I discovered that the right side rear sway bar link bolt wasn't torqued...it was very loose...a few more turns and it would have fallen out. It really surprised me the factory could miss it....but anyway, you guys might want to check yours. I still need to check my motor mount bolt. Now I'm a little more motivated.(boom05)
