Okay, so what you're looking at is not a car from The Jetsons. It doesn't fly and it doesn't fold into a briefcase when you get to your office in the sky. But it might as well. What it is, in fact, is a one-of-a-kind prototype made by Pininfarina – the same company that designs every Ferrari – in 1960 to demonstrate what was possibly in advanced aerodynamics. And now it's up for sale.
Called the X Concept, it has a unique wheelbase with one wheel front, one aft, and two near the center. It has a drag coefficient of 0.23...that's lower than a Toyota Prius, one of the most aerodynamic cars on the road today, but this was done fifty years ago. Only one was ever made, and the Aero Toy Store in Fort Lauderdale, Florida, has it for sale with a price tag of $3 million. JamesList has it listed from the same dealership for $1.3 million, so it looks like the steep price is negotiable.
