1. BMW 635 CSI

BMW presented the new 6 Series in 1976 as their entry in the Gran Turismo market. Also, it was one of the most elegant coupes of the period. It was famous for its recognizable design, four headlights and big BMW grille. Interestingly, they built the 6 Series on the 5 Series basis featuring powerful six-cylinder engines.

The 6 Series proved to be popular, spending over 13 years on the market. BMW managed to produce over 100,000 copies that are still sought-after models in the used car market. Interestingly, more than half of the examples they produced they also sold in the USA. Although the prices are still reasonable, soon these elegant cars will be out of reach.
