The Ford Pop was a cheap car for the UK, the only one under £100 for quite a while. Just like Ford in the US though, they tried to keep it going for arguably too long, this was still being made in the 1950s
It had quite a few compromises - the weezy sidevalve, 3 speed gearbox and solid axle suspension (the front suspension could be upgraded using a Bellamy swing axle conversion).
The biggest limitation was the manifold driven wipers - the fast you went, the slower they wiped
The same drivetrain was kept weezing away under a new body right into the 1960s well after the Mini was being made.
