Roadster Double Donut

Roadster is the North American term (spyder in England and a spider in Italy) used for a 2-seater lightweight car without a permanent top. The term was also used for a light carriage, synonymous with "buggy".

Even with the soft top convertible raised and deflecting "windows" (if existing) snapped in, the driver and passenger remain somewhat exposed to the elements. "Convertible" is an abbreviation of "convertible coupe" or "convertible sedan" which in 1920s-30s parlance indicated that the top of the car can "convert" the car from a car with the passenger habitacle covered into a car without having the passenger habitacle covered, transforming vehicle into a "cabrio".
