Mercedes-Benz W140 S-Class & CL
The W140 was one of the most over-engineered cars Mercedes-Benz ever built, with double-pane side glass, soft-close doors and, in the V12 cars, one of the great engines of the 1990s. It came as a sedan and as a coupe, sold as the SEC, then S-Class Coupe and finally CL.
The V12 S600 sedan and the CL600 and S600 coupes are the most collectible, with the V8 S500 and CL500 close behind. Low miles and a complete service history matter enormously: these are complex cars and buyers want proof they've been cared for.
