Yes CLK63 Cab is in the US. They are also making a limited run CLK63 Black Series Coupe (adapted from F1 Safety Car). Almost all AMG's that were formally 55's are now 63's with exception of S, CL, SL (65's). 65's are based on the V12 whereas old 55's were supercharged V8's and now current 63's are NA V8's.
