Mercedes S-Class AMG Sport Edition – it’s another S-Class run-out special

The Mercedes S-Class AMG Sport Edition is another ‘final’ S Class model with extra equipment as the W221 comes to the end of its shelf life. The current Mercedes S-Class (W221) has been with us since 2006, despite which it’s still a fine car (and a great secondhand buy), but it’s about to be replaced by an all new S-Class. That’s why S-Class sales are falling and why Mercedes has rolled out the S-Class Grand Edition and CL Grand Edition to persuade buyers that a new S-Class (or S-Class coupe, in the case of the CL) is still a good place to park a sizeable chunk of change.

Concept Car of the Week: AMC Amitron (1967)

While the American auto industry spent most of the late ‘60s creating huge barges powered by monstrous engines with loud decals on disco paint jobs, AMC believed in the future of compact cars, fuel economy, and go-faster stripes. Designed under Richard Teague's supervision, the quirky Amitron was unveiled in 1967 in a hotel in Detroit. Measuring less than 2,200mm long, it is 350mm shorter than a Smart Fortwo and its wide track gave room for three passengers seating abreast.
