With some W140 coupes (500SEC, 600SEC, CL500, CL600) hovering around $10,000, they are quite affordable. Every time I see one, I'm reminded of my strong belief that it is the ugliest Mercedes ever made.
It looks big (in a bad way), unruly, and blunt. There is zero sophistication.
What I dislike most about the W140 coupe is the thick black gap that separates the trunk lid from the rest of the rear end. It looks crude.
