Roadster, 4-door sedan, sports saloon.
Beginning of the five-bearing eights, good for over 70mph on 77bhp. Styling's the same as in 1930, though you don't get the latest synchromesh on cheap Buicks till mid-season. Wire wheels and sliding roof optional on British-market cars: sports saloons (British bodies) were fabric or semi-panelled.
