The good people at Cars.com have slogged their way through sales data from April and found something interesting. The Toyota Prius Plug-In managed to walk away as the third quickest-selling car in the U.S., spending just five days on dealer lots. That figure was good enough to land it behind the BMW X3 and X5, both of which take four days to find a new homes. The plug-in hybrid has only been on sale for two months, and took the honor of being the second-quickest selling vehicle in March, according to Cars.com. Funk Flex
