This is a very interesting concept. To me however, there appears to be a bit too much AMC Gremlin in the concept, and the design is too far alway from BMW design, if you look at the strange intrepretation of the Hoffmeister kink.
Absolutely stunning. It's built on the new Z4 chassis. Would be nice if the M division could take the current Z4, make it into a M version, with this bodywork. I would buy it.
