Not a fan at all. Looks like a smaller 6 from the rear, which is it's only saving grace. Everything aft of the a-pillar looks disproportionate and way overdone. The tacky fender badges designating the model trim are the nail in the coffin.
The M4 has tonnes of ground to make up for this debacle, IMO...
