On any other car I would agree with your DIY project. But this MB clutch needs "special" tools that adjust the tolerance, not to mention just removing the throw-out bearing. I would take the car to an independent MB mechanic to have this done unless you own a shop... Definitely DO NOT have a Chrysler Dealer do the work.

Last time I had the clutch replaced, labor was $1,300. The Spec racing clutch was $1,100, new throw-out bearing was $120 from MB.
