Considering this as a potential replacement for my 204 C63. Love the new E63S but prices are silly. 205 C63 S coupe is also beautiful but again the right spec is silly money and not many with good spec for sale. So this brings us to the F, anyone drive one? Would have to be the supercharged R with 4 wheel drive. Coupe or cab, don't mind. How fast are they and what's build quality like? Any other recommendations? Would like something performance, reliable and rare. Ideally German..
