1970 Pontiac GTO Judge Ram Air IV Convertible – 17 BuiltAs one of the rarest and most sought after Pontiacs ever built, it's no surprise that the 1970 Pontiac GTO Judge Ram Air IV Convertible is expensive. However, even the most seasoned Pontiac collectors must have been shocked to see one example sell for $1.1 million in early 2023. That makes it the second most expensive Pontiac ever sold, only behind the one-off 1954 Bonneville Special Motorama Concept Car. Most examples of the Judge sell for an order of magnitude less than that figure, but the record-breaking example's exceptionally rare spec is what made it worth the cash to one particularly wealthy collector. Only 17 examples of the 1970 GTO Judge Convertible were built with the Ram Air IV option, and of those 17, a mere seven were equipped with an automatic transmission. The example in question had also benefited from a full restoration, leaving it in showroom condition. It wasn't the only GTO Judge Ram Air IV Convertible sold that year either –- another of the 17 sold at the same auction for $572,000, while a third example appeared at auction in May 2023 and sold for $445,500.
