I don't know, the Stinger looks proper, yet, to me, it doesn't have the appeal of the lines on a Corvette or a Nissan Z (Z33 and Z34). I like its long-ish hood and the longer distance of the fender area between the front door leading edge and the trailing edge of the wheel well opening. I like the fastback.
I don't hate it, yet I'm not enamored by it.
