What body style is this and what is it properly called. ANDY

 

Looks like a Cutlass S

 

Nice car. what year is it? 73, 74? counting from the left, 3rd and 4th numbers are 37 it is a Cutlass Coupe, 57 it is a Cutlass Supreme Coupe. GM also refers to it as a Hardtop Coupe. Sometimes GM is all over the road with their body style descriptions. Originally a hardtop meant no B pillar and coupe meant only one seat, two passengers. Is the car in England?

 

It's not a 1973 since it has the 5 mph back bumper (FYI, the law was 5 mph front bumpers in 73 and front and back in 74-up). It's also not a Supreme since it has the fastback body. It's a Cutlass Colonnade Coupe.

 

Looks like a 75 Cutlass S coupe to me.
