Yep, I'm lucky enough to have been offered one of these by my friend. Started life as a C43 in '99, the engine then junked without turning over and the 5.5 dropped in. He picked the car up from AMG himself and has owned until now 110k miles. As far as I know it's a pretty rare car and obviously given the milage and the car's life I'd love to know what I can expect would need replacing and what would be a sensible way of upgrading those components likely to fail. Can anyone help me out here? I've searched the forum and can't find any references to factory W202 C55's. The car still drives well, it feels pretty tight, thouhg I suspect the gearbox may be on the way out (what are my options here?). The engine still pulls magnificently, but the twin exhausts have been damaged slightly in a knock. Can someone recommend a replacement? Any major engine maintenance in store for me soon?

Many thanks...
