Saloon.

Styling is englarged 4/44, there's a new torsion-bar front end and a coil-sprung live back axle, and the twin-carb engine is the BMC C-series. Four-on-the-column - unlikely Riley Pathfinder sister, which shares basic structure/mechanicals (engine apart); overdrive optional on last S1s. Usual wood and leather, although the dash is plastic.
