This GLC is a mid-sized SUV, but obviously one with a premium badge. In the Mercedes-Benz SUV hierarchy, it slots in just above the smaller GLA but below the brand's really luxurious and pricey 4x4s - the GLE (aimed at BMW's X5), the big 7-seat GLS and the really hard-core go-absolutely-anywhere G model. The GLC aims to combine the best of all these models and in this enhanced form is smart, efficient and very desirable.
