The first £100 car

Automaker Morris first achieved the goal of a £100 car in 1929, even then it was just a barebones sidevalve 4 cylinder 2 seater with black rad and trim with only basic lighting, not much more than a cyclecar. Adjusted for inflation that is £6,170.07 (about $10,000 CDN) in modern money.
 The nice cutaway drawing is the work of John Ferguson whose work shows up from the mid 20s till the '60s.
