What more could you want? It's so beautiful that it draws a crowd in parking lots. It's as quiet and comfortable as a sedan with the roof closed. The interior is gorgeous. The new cup holders remove all complaints of the old ones. The performance is more than adequate. While I would have liked some of the added features of the CLK500, I don't feel its additional power is worth the price difference, or is needed. And the AMG version? Why?
Interior design. Navigation system. Operation of the top.
After two months in this car, I can't think of any.
