Never heard of a Shotwell? Well, neither had we—and neither had Jay Leno, at least not until about 15 years ago.

That's when the TV funny man received a letter from a man in a small town in Minnesota. That man--Bob Shotwell--told Leno that he had designed a car back in 1931.

Not only did Shotwell still have his three-wheeled car, he wanted it to go to Leno himself.

Building a car yourself isn't for the faint of heart, but that's just what Shotwell did more than 85 years ago on a suggestion from his father. As Leno tells the story, Shotwell's dad told his high school-age son that if he wanted a car, he needed to build it himself.

It's unlikely that father expected son to follow through, but that is exactly what happened. 

The three-wheeler is powered by a 77-cubic-inch Indian motorcycle engine and it is an interesting, if not exactly innovative, design. Still, for a 17-year-old kid, the little car is a heck of an achievement.

Shotwell drove the car more than 150,000 miles, including a 6,000-mile roundtrip journey to the Northwestern United States. 

In 1999, Shotwell decided that the car needed a new owner, so he passed it to Leno under the condition that it not be destroyed.
