Merc GLA The Mercedes-Benz GLA will be many things to many people, but not large or spacious. But this compact, good-looking SUV will have reasonable interior space, good dynamics and good ground clearance. Expect to see the same engines and transmission as the CLA, the 1.8-litre petrol and 2.4-litre diesel with the 7-speed automatic or the new 8-speed automatic. Stylish and practical? Yes, the wait till it releases towards the end of the year is going to kill you but will probably be worth it.
