Project Car: 2011 RTR Mustang Farewell One last look at our 2011 5.0 Mustang GT Project Car. It was sent off in style at Mecum Auto Auction and we just wanted to give you guys one last look at the Mustang because it is now officially retired as a project car. This car was fun to beat on. Had plenty of seat time at the road races, and the drag strip. I know I will miss this car for sure.
