The value of the 918 Spyder is closely tied to its exclusivity and its speed. While owners of lesser Porsches may come across similar cars when cruising around town, 918 Spyder owners should have no such experiences. With a base price of $845,000, it's sure to be one of the rarest cars sold in America. It is also one of the fastest cars sold in America with a top speed of well over 200 mph. However, it does also offer a degree of practicality, with all-wheel drive and the ability to switch to full electric mode for quiet cruising around town. Drop the hammer however and the 918 Spyder will treat drivers to an experience that can't be replicated anywhere at any price.
