A lot of people have hobbies they are really passionate about, but few are as awesome as this.

Ernie Adams has devoted countless hours to building miniature retro cars. Think of model airplanes where everything is built to scale, except these things are actually drivable! 

The first one he built was constructed from scrapped refrigerators! The ingenuity needed to build these things is astounding when you consider the level of detail in each car.

Over the years, Ernie has amassed a collection of hundreds of these miniature cars, which he claims has consumed between 3,000 and 4,000 hours of his life.

At this point, calling it his hobby is a tremendous understatement.
