Also considered yo be one of the most bulletproof engines MB has made in the last couple decades (along with the 3.5 v6 variant).

Motor mounts are commonly collapsed at 100k, I had an issue with the starter (hot starts) and there is a somewhat common failure of the intake manifold flaps...new pierburg units are like $700. Other than that, dependable, powerful, fast, and reasonably economical for what it is (I get 26-27 highway on my 4matic).

Get rid of the runflats. Idk about the coupes but my sedan has a spare in the trunk, if you have the space you could probably find a junyard unit without too mucb trouble.
