@71Polara -- thank you for posting DE43G1F242070 's fender tag. Your Dodge Polara is a four-door hardtop. Production numbers are
here.
As
@detmatt has noted, yours is a low production model: only 2,487 were made. In contrast, 7 times as many Polara Custom 4-dr hardtops were made. That is because your model was the entry level senior Dodge in 1971 (DE, for Dodge Economy), and as such the folks buying the car went heavily for the sturdier, cheaper 4dr sedan -- of which 21,578 were made in 1971. The sedan/hardtop ratio is almost reversed for the Polara Custom (DL, for Dodge Low) -- and there were no sedan offering (only hardtops) for Polara Broughams (DM, for Dodge Medium).
