14. 1966 Pontiac Bonneville
The success of the GTO affected the whole Pontiac range. Suddenly, Pontiacs became sportier and more powerful and aggressive. Even the four-door sedans became performance machines. The biggest, most luxurious Bonneville is the best example. Pontiac restyled the Bonneville for 1965, but in 1966 the design matured.

The Bonneville evolved into an elegant, low, sleek form, which was perfect for this performance sedan. Bonneville came as a hardtop with Pontiac’s signature wide-track design, split grille and nine bolt wheels. Customers could get lots of optional equipment and powerful engines, too. The 389 V8 with 325 HP was standard, but you could also get a mighty 421 V8 with the famed Tri-Power option delivering 360 HP.
