The A-Class is the smallest - and most affordable - model in the Mercedes line-up. As a small family car, it's an alternative to models like the Audi A3 or BMW 1-Series, but it's unusual upright styling makes it look more like a people carrier.

Although the original A-Class was infamous for rolling during the 'Elk Test' before it was significantly re-engineered, expect high standards of safety in the new model. It achieved the maximum possible five stars in the Euro NCAP crash test. A notable safety feature is the double layer floor which pushes the engine under the passenger compartment in the event of a frontal collision and there's plenty of safety equipment (although only four airbags as standard).

Mercedes doesn't provide dead-locks on its cars claiming these hamper rescue attempts in an accident scenario.

The previous A-Class was quite problematic, but this one has proved much better with no significant problems reported.
