We'd like to thank reader Nathan C. for uploading this video and sharing it with us. Not since a woman mistook a Ferrari F430 for a Ford Mustang have we seen a car spotter fail so hard. Now mixing up a Ferrari and a Ford is pretty bad, but thinking a Porsche 918 Spyder is a Corvette may take the cake. Even if you don't know your cars, the back of the 918 literally has the supercar's make and its manufacturer written on it in big letters. Lucky for this woman the driver of the 918, the Weissach-equipped number 731, wasn't an ass.

Check out the video and remember that when it comes to car spotting, any and all fails will live forever on the Internet.
