Ken Imhoff must have really, really, really wanted a Lamborghini Countach. But at about $100K used, he decided that he'd make one himself!
Here's Ken's Countach, which took him over 10 years to make (he had to dig it out of his basement to get it out!) at Jalopnik: Link | More pic at Lamborghini Replica (surprisingly, a lot of people are making their own Lambos!)
Update 10/29/08 - Ben Wojdyla, who wrote the article linked to above wrote to us that Jalopnik has an in depth interview with Ken: Link
