10. Ford Mustang II
The second-generation Ford Mustang arrived in 1974 and was on the market for four years until 1978. Despite the fact that it was the subject of so many jokes and even bad press, the Mustang II was an important model. The downsizing of the whole Mustang range, introducing economical four-cylinder engines and parts sharing with other Ford models helped it survive the recession of the ’70s and the death of the muscle car movement.
But besides all of those facts, there’s no denying that the Mustang II was downright ugly in comparison to the late ’60s and early ’70s Mustang models. Thankfully, Ford kept the Mustang II in production for just four model years, eventually moving on to better-looking, more powerful Mustangs.
