20. Austin A90 Atlantic
The UK car industry relied heavily on exporting in the post-war years because it was the only way to survive in a changing market. Realizing that America was the biggest, most profitable market, Austin decided to present a nice-looking convertible they designed especially for U.S. buyers.
They named the car the Austin A90 Atlantic. It had nice features, a 2.6-liter straight-six engine, and decent power. It should have been a success, but it failed miserably. Austin made around 8,000 of them, but only 350 ended up in the states.
