I saw what you did there, RC.
The petrol tank and wheels of this Mazda (model designation "Mazdago" must've looked very futuristic in the early 1930s.
It's difficult to gauge the size of Mazda's three-wheelers without seeing it next to other cars. They're far bigger than Reliants or Bonds. Take, for example, the Mazda T2000 from the 1960s/70s. This feature shows that its longest version could measure almost 20 feet:
Classic Car Buyer states that Mazda didn't branch out into passenger cars until 1960, when it produced the R360 (which had a 356cc V-twin mounted in the rear).
And, of course, Mazda was successful in selling vehicles with rotary engines, which is more than can be said for Suzuki or DKW.
