Not trying to be a jerk but the quarter window is the same size as a 39 chevy/pont/olds yet the roof flows into the rear quarter there for it can be non other than 37/38 buick or pont the rear quarter molding fits 39 chevy coupe and 4 doors yet the roof flows into the quarter where the 39's have a defined break at the beltline. there is a slight chance it could be a caddie i but the hood looks short on that note the hood is def not 37 chevy or 39 but looks buickish
You can tell it's a turbo coupe? It does look more like a Cad/LaSalle than a chebby... I wouldn't care what it is I'd try n get it out of there..
