A Mercedes-Benz GLC near-production prototype fleet has been spied inside and out. As you already know, the German model will replace the LK and comes with a more curvaceous body. 
The prototypes that have been spied features a couple of disguise things on bumpers and lighting clusters, but the interior was fully exposed. 
Judging by these pictures, the upcoming Mercedes-Benz GLC has the same C-Class interior and this shouldn’t come as a surprise since the crossover is based on the W205 model. According to rumors, the upcoming Mercedes-Benz GLC will also borrow the engine line-up and gearboxes from the sedan.
The new Mercedes-Benz GLC will be officially unveiled on June 17. Stay tuned for more details.
