1. Peugeot 504 Cabriolet
What appeared to be a sporty roadster was a lie in the disguise of a roadster. The 504 Cabriolet was a sad excuse for what a good roadster could be. The first problem here was the extremely lightweight and cheap design. When you drive a convertible you want to feel like the car is going to remain on the road as you take twists and turns. Aside from that little problem, the 504 Cabriolet was extremely lethargic in terms of power. In fact, the thing had lackluster acceleration time at best.
These cars were not too popular because of the problematic engine and the cramped inside. If you are looking for a quintessential ’70s roadster, the 504 Cabriolet is one you should avoid.
