The Ten Craziest One-Off Cars Ever Built

10.) Blastolene Tank Car

Suggested By: ForzaFanatic3

Why it's deranged: Legendary builder Randy Grubb took an M47 Patton engine, twin-turbocharged it to 1,600 horsepower and 3,000 lb-ft of torque and built a hot rod around it. The whole thing weighs around 9,500 pounds.

9.) Pininfarina P4/5

Suggested By: waveridin1959

Why it's deranged: Any car enthusiast should be happy with an Enzo. It's stunning to look at, fantastic to drive, and has one of the greatest reputations in the industry.

James Glickenhaus was not happy with an Enzo, and instead got Pininfarina to rebuild one into the lighter, faster retro-futuristic P4/5. He did build a sister car, but it was based on an F430 for road racing.

8.) Maybach Excelero

Suggested By: McLarry

Why it's deranged: Maybach is dead, but the Excelero will never die. It was built to test tires at high speed, show off how much that Benz V12 can do, and generally look like the most badass thing on wheels.

Birdman tried to buy it, but since that didn't work out, it remains in the Jalopnik Fantasy Garage.

7.) The Basement Lamborghini

Suggested By: SarDeliac

Why it's deranged: Most of the cars on this list were thought up by gentleman wealthy enough to get a car company or coachbuilder to design them a car. Ken Imhoff saw Cannonball Run and wanted a Countach of his own, but he didn't have the money to go out and buy one. So he built a Countach. In his basement.

We consider it a greater car than anything ever built for the Sultan of Brunei, who leaves his cars to rot like a dirtbag.

6.) Colani Corvette Charisma

Suggested By: TwiceAroundTheClock

Why it's deranged: Most of Luigi Colani's insane one-offs are non-functioning design studies, like his twin-hull Miura prototype. In 1989, however, took a very functional Corvette and turned it into this, the Corvette Charisma. It's like the world's fastest guppy.

It toured the US explaining Colani's organic design style, and with a 1995 re-bodying, it hit 230 miles an hour at Bonneville.

5.) Phantom Corsair

Suggested By: CrzRsn

Why it's deranged: The Phantom Corsair was supposed to be a production vehicle. The man behind the project, Rust Heinz of the Heinz family, was going to make a ton of these 190 horsepower streamliners, but only one got built in 1938.

Perhaps people were frightened by the fact that it looked like a death machine from the future.

4.) Presidential Cadillac Limousine

Suggested By: ForzaFanatic3

Why it's deranged: Take one industrial-grade GMC TopKick. Stretch an armor-plated Cadillac body over it and you have Obama's Cadillac One, or as it is affectionately known The Beast.

3.) Brooke Swan Car

Suggested By: Richard Bartrop

Why it's deranged: It's the star of the show at this year's Pebble Beach, it was built by an eccentric British colonialist in India, 1909-1910, and yes, it craps whitewash.

2.) GM EcoJet

Suggested By: OMG, TTA!

Why it's deranged: Jay Leno, rich gearhead that he is, asked GM to build him a ecological supercar.

GM gave him a Corvette with a 650-horsepower helicopter turbine in the middle. It runs biofuel and is bodied in carbon fiber. We wish we had money for a project like this.

1.) Cadillac TAG Function Car

Suggested By: Jordan Hewlett

Why it's deranged: Nobody builds customer cars with quite the same panache as Switzerland's Franco Sbarro, who topped himself back in 1978 with this 23-foot Cadillac shooting break.

It was commissioned by Joseph E. Adjadj, the owner of the brand TAG, as a sort of rolling office. It has four chairs, two phones, and was designed to have two secretaries onboard. Sbarro bought the car back and it hasn't been sold since.
