Like for like the Germans are lagging behind Lexus and Infiniti. In terms of quality of the interiors. The c63 has the same interior as a regular one, nice but nothing special and not the best quality materials. Even the 7 series interior is being given a run for it's money from the Infiniti M range, my dads owned more 7s than any other car and although they're very nice they just don't have the wow factor, no BMW interior does
....I should apply for Infiniti sales
