Shots of this clay model concept known as the Proton PM5 Concept has been surfacing in forums lately. Some say it is a future model that Proton has been developing together with Lotus, and others are of the opinion that it is an old design concept for the recently launched Lotus Europa. Anyone know more about this concept? There are some hints of Aston Martin design cues especially on the rear end.
