Character

M271 EVO (CGI turbo)

"Turbo CGI successor to the Kompressor. Toothed chain fixed the stretch problem, but camshaft adjusters and tensioner wear early — Mercedes extended the adjuster warranty to 10 years in the US. Budget for the timing job."

M113

"The V8 workshops call indestructible. Valve-cover gaskets weep and the crank sensor dies when hot; otherwise 250,000 miles is routine. Supercharged E55 ML (476-500 PS) is a different animal and not covered here."
