Take a look at these sketches and renders of the next generation Mustang by designer, Frank Wu. The renders were done in 2010 at the Ford design studio in Dearborn, MI where Mr. Wu was a design intern. While not new, the sketches show interesting concept designs of both the exterior and interior of the Mustang GT and GT500 that are worth a revisit. Let us know what you think!
