With the Porsche 911 history now five decades deep, it’s amazing how the company has kept the styling so similar when comparing a 911 of today. German-based tuner DP Motorsports has celebrated the 40th birthday of the notorious model by transforming a 1990’s Porsche 964 into a 1973 Porsche 911 Carrera RS replica. From new school to old school, both the exterior, interior and engine bay received a wide range of aftermarket parts in the build.
