Real MPG

40.3

Average

Folding metal hard-top roof offers security and refinement, performance AMG SLC 43 delivers pace to worry Porsche, optional Airscarf allows open-top motoring even when temperature drops.

Boot space is heavily compromised by lowering the roof, ride quality is harsh on all models, and worse with AMG suspension, dated dashboard betrays the age of the car underneath.
