My 2 cents: the 43 is all around more fun, 63 makes nice noise.
Both have terrible transmissions and the 63 has especially terrible power delivery.

C63 dynamics/steering are so shit that it makes a Challenger feel like it has balance.
Car and Driver says the Challenger stops better, MotorTrend says it does figure 8 faster.

Personally, E63 is the top preference, followed by C43 and C63 last.
The E gets more tire and the shit steering/dynamics are more forgivable with a better comfort/interior.

I never thought about that. I should sign up for identity theft insurance.
