Riley 9 Monaco. (1930-31)

After three years of sales success, the Monaco was improved for 1930, with a new full-width rear boot, new roofline, bigger doors to help entry, and new rotax headlamps. The result was a more pleasing design, especially with the introduction of a metal panelled version a year or so later.
The updated Monaco continued to be a strong seller, with perhaps 1500 built in a single year of production.
