30. Citroen 2CV
Even though the 2CV was one of the best-selling cars in Europe, it was still a terribly ugly machine. The idea behind the Citroen 2CV was to present the most affordable family car possible. It would be minimalistic and utilitarian, but still, have a certain level of comfort. Also, it had to have enough space for four occupants and their luggage.

The construction was extremely simple and durable and all 2CVs had their canvas top. But because it was an economy car, Citroen obviously forgot to invest in its design and development. However, despite its shortcomings in the looks department, the Citroen 2CV still managed to stay on the market for decades.
