They can run over 500rwhp with tune and full bolt-ons and trap high 120's / low 130s. Can also run well on a track.
The new AMG PP with the MCT and new interior have corrected all the faults I found in it the first time I drove it.
Kenny - I want my Z4MC back too... ideally, I get that back and keep the C63.
In Canada, the C63 AMG with all options is cheaper than a M3. So, it would not have "lost" C&D's compro!
