Totally agree w/your points. SL55 is a phenomenally great high speed GT/commuter car w/convertible appeal (big advantage in sunny climes)....and a relative bargain at $130K. SL65 just adds some muscle for autobahn bursts from 100-155MPH (not sure if ROW relevant). SLR sounds like an expensive mongrel not particularly adept at supercar/GT/commuter duty. Given most SL55 enthusiasts have other toys in garage for fun driving, I doubt SLR makes the cut. Plus, end of day, brand is important, esp if car's technology and performance is sub-class, $400K for a DC???? SLR will likely have weak resale value.
