At this year’s Goodwood Festival of Speed, Ken Block gave the event’s host, Lord March, a ride in the Hoonicorn, a ride Lord March won’t soon forget.

Before the Hoonicorn became internet and automotive legend, it had to get shook down. Here, in all its ridiculously awesome, unfinished glory, is Ken Block performing said shaking.

You’ve seen it “Wild in the Streets” with the Gymkhana 7 video, but now here are the details on the star of the show. This is Ken Block’s 1965 Ford Mustang, known as the Hoonicorn RTR, and here are the details you’ve been looking for to make your own … if you have a few hundred-thousand to spare.
