This car is owned by Phil Sohn, he's big on Rotary powered cars and also owns 2 RX7's, one of which is constantly evolving into a new and amazing build every year it seems.
These pictures are in fact the same car, the Blue paint version is the original factory paint for this car, more often than not the car is wrapped in vinyl, dramatically changing its look, but also protecting that original paint.
