Most of you probably have no idea what a Lamborghini Reventon Roadster is, and that's because it is one of the rarest models ever made by the supercar company. This 2010 beauty only had 14 brothers and sisters, so seeing one for sale is pretty much like seeing a unicorn prance through your backyard and kick your puppy (we don't even know what that means, but just roll with it). In nearly four years, this specific Reventon Roadster has only been on the road for 10,000 miles, which only makes it worse for your pockets. To own this 670HP machine (with a 6.5-liter V12 and a top speed of 205MPH), collect your pennies to the tune of $1.7 million and head over to Super Vettura to make it happen. You most likely won't have another chance.
