It wasn't that many years ago the Dino 246 was not seen as a legitimate collectible car. In many cases, Ferrari owners would argue over it's provenance, with it's Fiat involvement, and Non-Ferrari badging. Plus with the small displacement V6, it isn't particularly quick, so performance enthusiasts often ignored it as well.
As recently as the mid 90s, an example in good condition was able to be purchased for less than a new Camry. By the early 2000's, they were breaking six figures. In the last two years, the prices have skyrocketed into the $300-450,000 range. Perhaps the collectors are appreciating that Dinos are nothing if not visually beautiful cars, even if their provenance is not as pure as otherwise more collectible Ferraris. But before the Leonardo Fioravanti-designed Dino 206/246 was released in 1968, there was the stunning Dino 206 Competizione Prototipo.
The 206 Competizione is the only one in existence. It's also the only one ever made. Based on the chassis of 1 of 18 206SP sports racers produced in 1966, it was shipped off to Pininfarina to receive a custom body. Ferrari asked the design house to build them a road going supercar using race car engineering and technology. The task fell to Paolo Martin. He was new to the Pininfarina team at the time.
While Martin borrowed much from the 206 Sports Racer form, the Competizione carried some distinctive features, such as gull-wing doors. Martin's original design did not feature wings. They were added later because Pininfarina was convinced the wings helped the perception they were more at the forefront of racing technology.
The final car debuted as a fully functioning prototype at the 1967 Frankfurt auto show. The engine was the same one used in one of the three Dinos raced at LeMans in 1966.
The 206 Competizione design exercise was never intended for production, but many of the design elements clearly influenced the beautiful 1967 Dino 206 GT - a car otherwise clearly based off the 1965 Berlinetta Speciale.
Turin-based Pininfarina typically keeps such special cars in their own private museum, but in this case they decided to offer famed Ferrari collector James Glickenhaus the opportunity to purchase the 206 Competizione in 2007. Fortunately for us, he purchased it, and has made it far more accessible to enthusiasts by driving it regularly, and entering it into shows.
