GullWing BMW M6 from Curve Auto Design
Although not very well known outside of Japan, the local tuning specialist Curve Auto Design has a good reputation of putting gullwing-doors on anything that has four wheels and an engine.
The latest example of this is the latest BMW M6 super-coupe and the 645CSI tuned to order.

Besides adding the gullwing-doors, the tuning was very subtle.
Designers at Curve Auto Design have only introduced some small modifications to the original front and rear spoilers, added a couple of small air intakes to the body near the rear fenders and a small aileron made of carbon fiber.
The rest goes pretty much unchanged. But, as one can see, the M6 gets completely new, much more aggressive and self-confident, look and feel.
