Platform Heritage

The Mercedes-Benz GLA is a subcompact luxury crossover SUV manufactured and marketed by Mercedes-Benz over two generations. It is essentially the SUV equivalent of the A-Class, and the smallest SUV marketed by the brand. The production version was revealed in August 2013 ahead of the 2013 Frankfurt Auto Show in September 2013. The GLA is powered by a range of petrol and diesel 4-cylinder engines, and comes in either front-wheel drive or all-wheel drive, the latter marketed by Mercedes as 4Matic. The GLA nameplate aligns with Mercedes SUV nomenclature, where GL stands for Geländewagen (German for off-road vehicle) and the A designates its overall place in the Mercedes range, in this class, the smallest or A-Class.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
