Hello M5BOARD, I'm looking to get an E63 M6 or a Mercedes C63 AMG. What things should I look for when test driving an M6? Should I avoid SMG or get a manual? The closest 6MT I've found is 1500 miles away from me (2008 black on brown, 38K miles). Is this car really that expensive to maintain? I know the C63 AMG is pretty bulletproof but I love the S85. Should I get the M6 or is this car too expensive to maintain? Yes I used the search function but wanted some input on C63 vs M6. Thanks!
