When it comes to iconic sports cars, Porsche is one of the top contenders. Over the years, Porsche has consistently built some of the best cars in the market.

The German car company was founded on April 25th, 1931, in Stuttgart, Germany, by Ferdinand Porsche. The company has a history of designing and building some of the most amazing special edition cars.

These cars range from one-off custom creations to phenomenal homologation specials for their different motorsport icons. These rare cars are some of the most sought-after collector's items.

The Porsche 935 Street is a one-off build. This was the first car that was built and produced by Porsche Exclusively for Mansour Oijeh. Mansour is the founder of the TAG Group and a huge Porsche collector.

The boxer engine was paired with a four-speed manual transmission that used Le Mans racer gear rations. There have been numerous replications of this car, but the Porsche 935 Street is one of a kind.

The Porsche 993 Speedster was built by Porsche Exclusive using the 356 Speedster as their inspiration. Only two units of this car were ever built, so it's no surprise that not many people know of its existence.

One of these cars was built for Ferdinand Porsche’s grandson Ferdinand Alexander Porsche for his 60th birthday. The other was given to comedian Jerry Seinfeld in 1998 as a recognition of his status as an avid Porsche fan and collector, owning of one of the most impressive Porsche collections in the world.

The Porsche 914/8 is the first road-legal car to use an eight-cylinder engine. The two units of the 914/8 were built for Ferdinand Porsche’s sons Ferry Porsche and Ferdinand Piech. While these cars look the same on the surface, they were quite different. Piech’s orange 914/8 was powered by a 3.0-liter air-cooled quad-cam 908 racecar engine that pushed 350 horsepower. It was said to be quite a handful.

Ferry’s silver914/8 on the other hand was lighter and more refined. Its handling was better compared to his brother’s. The engine on Ferry’s car was detuned and pushed only 300 horsepower.

The exact number of the Porsche 964 Turbo Cabriolet has always been something that Porsche enthusiasts have failed to agree on. Some say that only four original units were produced and that the other four are replicas. Others believe that eight original units of the 964 Turbo Cabriolet were built.

Nonetheless, the Porsche 964 Turbo Cabriolet remains an incredibly rare Porsche Exclusive build. Rumor has it that all the 964 Turbo Cabriolet units were built at the same time and that they were all sold by the late 1990s. So little is known about this car as Porsche has been very secretive about it, even going as far as archiving all photos of it.

13 units of the Porsche 991 Club Coupe were built to celebrate the 60th anniversary of the very first Porsche club. The 13 units represented the 13 founding members.

This car was mechanically identical to the 991 Carrera S. It featured a classic ducktail spoiler, Brewster Green paint, carbon-ceramic brakes, and a dynamic sports suspension. Under the hood of this beauty sat a 430 horsepower Power kit engine. Out of the 13 units, only 12 were sold. The remaining one was retained by Porsche.

The Porsche 911 993 generation is not rare, neither is the Cabriolet model nor is the Turbo model. However, a combination of all these is very rare. Only 14 units of the Porsche 993 Turbo Cabriolet have ever been built and produced by Porsche.

This German beauty was powered by a 3.6-liter turbo flat-six engine. This engine had a max power output of 360 brake horsepower. The Porsche 993 Turbo Cabriolet was the last air-cooled Cabriolet built by Porsche Exclusive. This car is a Porsche Exclusive build and is not officially recognized by Porsche.

Since Porsche set up the Porsche Exclusive wing in 1986, incredible limited edition custom models have been built for special clients and friends of Porsche. The Porsche 964 Speedster Turbo-Look is one of the many cars built for the chosen few.

When the idea of the Porsche 964 Speedster Turbo-Look was first brought up, Porsche promised to build 300 units of the 964 Speedster. After production, 936 units of the standard 964 Speedster were made, out of the 936 units, 15 units were taken by Porsche Exclusive for refinement. These 15 cars were given a new body kit that featured a widened Turbo shell. These special edition cars were the inspiration for the 911 Speedster Concept.

The Porsche 356 America Roadster weighed 1334 pounds and was powered by a 1.5-liter flat-four engine. This engine cranked up a max power output of 70 horsepower. This Porsche was not built for performance. It was more of a show car than it was a track car.

In 1984, Porsche built a special edition Porsche 911 for the Group B rally. This special edition car was based on the road-legal Porsche 911 SC.

This car featured wider fenders, a beefed-up suspension, and a lighter body kit. Under the hood of this beauty was a 3.0-liter flat-six engine that pushed 255 horsepower. Seeing a Porsche participate in rallying today is rare, but at its prime, the Porsche 911 SC/RS was phenomenal. Porsche built only 20 units of this car.

Today, Abarth is Fiat’s exclusive tuning division. However, back in the day, Abarth worked on a number of vehicles as they were building their portfolio. In 1949, Porsche requested Carlo Abarth to produce a lightweight body kit for the Porsche 356B Carrera. Porsche did this because they were too busy focusing on their Formula 1 exploits.

Carlos ended up designing and producing one of the most beautiful and iconic Porsche classics of all time. This ride was not just a beauty but a beast on the track as well. This car competed and won in its class at the 1960 24 Hours of Le Mans.
