It's a Triumph TR3A! The Zed Drei may say "roadster" on the doorsills, but a purist will point out that the Z3 has a folding top...and (optionally) a powered one, at that. A true roadster is an open car with only rudimentary, if any, weather protection. The TR3, for instance, had a pup tent sort of apparatus the occupants could erect that would valiantly attempt to keep most of the rain out of the now-notional "interior" and not blow right off the car at speed, but no guarantees were made.
They're so whimsical-looking when out and about in traffic, among the more normal transportation pods.
