IntroPontiac may no longer be making new cars, but its classics continue to hold a place in the hearts of enthusiasts across America. The brand boasts a slew of famous nameplates from the Bonneville to the GTO, the latter of which is widely credited with establishing the muscle car era. It wasn't always an easy ride for the brand, which saw its lineup stagnate thanks to underinvestment at several periods throughout its existence, but the best models from its glory days are becoming increasingly valuable collectors' grails. The most sought after Pontiacs now cost hundreds of thousands of dollars, and a couple examples have even crossed the $1 million mark at auction. Those prices put them well out of reach of the majority of Pontiac enthusiasts, but there are still plenty of the brand's iconic cars from decades past that remain attainable. There are far too many noteworthy Pontiac classics to make an exhaustive list of all of them, but each car in this selection of favorites is well worth its current value on the collector market.Pontiac Grand Prix Convertible '67The Grand Prix Convertible is one of the rarest classic Pontiac models, as it was only produced for the 1967 model year and in that time less than 6,000 examples were built. Per tradition, the '67 Grand Prix's styling had been given minor upgrades from the previous model year, with Pontiac carefully refining its famous "Coke bottle" styling that had first appeared in 1963. It was designed to offer a mix of both luxury and performance, being the perfect cruiser for weekend road trips or cross-country jaunts. Their rarity means that they command a significant premium over equivalent hardtop versions of the car, but they're still arguably well worth the money. Few cars of the era, American or otherwise, turn heads as consistently, and with more than 300 horsepower on tap, the model offers the performance to back up its show-ready looks. It's not known exactly how many examples survive today, but it's likely a fraction of the car's already small production run.
