The Pagani Zonda S 7.3 was made for one year only (2002) and because it's such a fine and rare piece of automotive machinery, few were built. It has one of the largest V12 engines ever made and was designed and built by those engineering meisters (which is German for masters, in case your reading of the language is weak today) at Mercedes-Benz AMG. Never shy of displaying their technical innovation, AMG added traction control in order for the car to handle the 547 hp.
It can go from zero to 60 mph in just 3.7 seconds and has a top speed of 220 mph. On paper, cars like this have no reason to exist. They're not fuel efficient and insanely expensive to buy and own. But that's precisely why us gear heads love and appreciate them. Most likely I'll never own one, but I'm sure glad it was built.
