I wonder if it could be a 1955 Jaguar XK140, Loewy Custom
Penned by Raymond Loewy who designed for Studbaker cars. He also designed among other things, steam locomotives, Hillman Minx, Lucky Strike Logo, Chubb logo, Greyhound busses, Exxon & Spar logos and the interior of Concorde.
The car is probably a 3.8 ltr 6 cylinder, infomation is a bit thin on the ground,
