Mercedes-Benz GLK-Class 
Launched in 2009, the GLK’s exterior has remained practically unchanged since then. Sure, the angles have been softened somewhat, but overall it remains quite square. A four-cylinder diesel base version is available, but there’s also a traditional gas-powered V6. Both versions of the GLK are equipped with a seven-speed automatic transmission, 4Matic AWD and the ECO system that cuts the engine when the car is stopped.

- Diesel drivetrain

Cons
