12. Austin Allegro
Small, fun cars were just hitting the market during the ’70s. Austin was a brand that specialized in these cheap and easy-to-drive cars. The Austin Allegro was a lightweight if not cheaply made car that was meant to appeal to the masses. In general, the car was lacking in a variety of areas such as craftsmanship and design.
Riding in the lightweight car was like being in a go-kart, and quality was lackluster at best. You don’t ever see these on the road anymore, and there’s good reason for that. If you want to get a paltry relic of the ’70s, then the Allegro is probably your choice. But if you want to drive a pleasurable car, the Allegro was a flop.
