There’s nothing to suggest that the GLA won’t be a reliable choice for customers looking for a premium compact SUV. Although it didn’t feature in our Driver Power satisfaction survey, the GLA’s smaller A-Class sibling finished in 36th position out of 75 cars, and Mercedes will be hoping the second-generation car will prove to be a more tempting proposition for potential buyers.

However, Mercedes could do with improving the overall ownership experience for customers. The car maker finished 28th out of 30 brands in our 2020 poll, and received particular criticism for high running costs.

Safety is an area where Mercedes customers can feel reassured. The GLA was safety tested by Euro NCAP in 2014 and received a full five-star rating, with adult and child occupant protection receiving scores of 96% and 88%, respectively. 

With lots of standard safety equipment, we would expect the revised model to perform just as well. The GLA includes kit such as a lane-keeping assist system, Active Brake Assist, cruise control, auto headlights and rain-sensing wipers. The Premium Plus versions also feature Traffic Sign Assist which is able to recognise speed limits and road sign information and display them to the driver. 


Mercedes’ warranty is a three-year/unlimited-mileage package. This is identical to the package supplied with Land Rover and BMW models, but goes one better than the Audi warranty, which limits cover to three years and 60,000 miles.


Mercedes offers its ServiceCare plans to help with scheduled servicing costs. Prices start from £30 a month, and you can pay either in monthly payments, or as a one-off upfront fee. If you buy your ServiceCare plan online and pay upfront, the manufacturer will offer a 20% discount on the total cost.
