I get that the C63 amg edition 507 is a great car and has the best hand built V8 engine but is it that good that even with a crappy automatic transmission it's better than an M4?
I'm obviously bias because I own an M4 and have never driven a C63 but I feel that the final result of the C63 wining the comparison is unfair when the M4 wins in suspension, breaking, transmission, price($10k less), technology and fuel consumption
