Why? Because he knew how.
Life isn't fair and not everyone can afford their dream cars. Sometimes, if you're fortunate enough, you can walk into any brand of car dealership and buy whatever you'd like. Nice dream, huh? But in case that won't happen, you'll either have to settle for something less, say a Mazda MX-5 instead of a Porsche Boxster, or nothing at all. Or, you could do something offbeat and completely original like this guy. He simply couldn't afford a Porsche 911 GT3, or probably any 911 for that matter, so he built one from scratch all by himself.
Only its underpinnings were recycled bicycle parts. Everything is custom here, from the body and frame to the "platform" itself. Nothing wrong with pure creativity.
