The Ferrari 250 GTO was first released in 1962 and is famous for its racing success in the 1960s. Only 36 were built, and that tiny number is a big reason why sightings are so uncommon. Collectors prize this car for its classic shape and its place in motor sport history. Recent auction records show values around $50 million or more.

Introduced in 1954, the Mercedes Benz 300SL Gullwing was one of the first production cars with doors that open upward. Its unique design and advanced engineering made it a standout when it was first sold. Today, finding one in public is unusual because only a small number of original models remain. Current market value for a well kept example can reach $1 million or more. The combination of style, engineering, and rarity makes this car a prized possession for classic car collectors.

Many 300SL cars have spent years in collections or on display at shows and museums. That means they rarely turn up in everyday traffic or at local events.

Most of the time it is preserved in a private collection or museum where only a lucky few get to see it.

Only about 300 of these were made, and many remain in careful hands today. Prices for a good condition 959 have been seen around $1 million or more in private sales. Because owners treat them as treasures, they are seldom driven on regular roads.

This car has a strong reputation among enthusiasts for bridging the gap between race tech and street use.
