Racing champion Jeff Gordon once did a "little commercial" with Pepsi and gave one guy the scare of his life.

Gordon and Co. went to a used car dealership, where he pretended that he wanted to test drive a car. Thing was...he was in disguise, so the car salesman had no clue that it was him, and Gordon took that guy on the craziest (and scariest) ride of his life.

When they posted the video, there were some people that thought it was a fake. So Gordon decided to prove to them it wasn't by doing the same prank to those disbelievers.

Check out the hilarious commercial...
