I saw the 2015 Mustang on Jay Leno's Garage. I think it would be improved by the addition of a passenger grab handle. Nearly all European sports cars have the handle and even VW has them. My wife cannot ride without holding on the the handle in our car. I once had a 88 Mustang and without power windows the space on the door was a grab handle. All Porsches, BMWs and the new Corvette have passenger grab handles. The Mustang would be greatly enhanced by this addition.
Thank you for considering my idea.
