1958 Ford Thunderbird
The 1958 Thunderbird is generally considered the worst year of the model’s design. It was a two-door convertible with a sleek, chrome-laden exterior with a long, pointed hood and a rear-mounted spare tire. The interior was equally impressive with luxurious seats, a dashboard full of gauges, and various modern amenities including power windows and air conditioning (via Supercars).
A V8 engine powered the Thunderbird and produced 300 horsepower, making it one of the most powerful cars of its time. The Thunderbird had a lot of different styles over the years, but this generation was the worst. With the front of the car turning many a buyer off, the styling of this Thunderbird was lackluster at best. Many others believe it was the ugliest Thunderbird and even one of the ugliest cars of all time.
