The 3 door might be a hit. I know Range Rover has a 3 door Evoque, not sure how sales are but people seem to love it.
there is a market for it. but its quite niche. the Evoque 2 door does sell. So I guess there is a possibility there is Mercedes wants to get in on the market.^ I have to agree with you on that one. In the past I have read the needs of the other two doors becuase of the inconvenience it causes for the passengers to get in the back.
Range Rover did it, this could be a good rival to their Evoque coupe. It's just one of those unique cars that would make the brand seem cool. A number of brands have their weird and unique cars.What type of customer would want to buy a 2-door CUV? I just have a hard time imagining the type of person who says, "This is exactly what I am looking for!" I don't see how this would appeal to people on a practical level.
