While we're guessing "working replica" might be a bit of a stretch, this full-size, drivable Tumbler
built by Bob Dullam in his garage is still quite the impressive piece of work, and will no doubt crush any eBay records set by home-built K.I.T.T.s
if it ever actually goes up on the auction block. Unfortunately, apart from the fact that it cost between $50,000 and $70,000 to build, there aren't many more details on the thing, but you can at least check out a few more pictures of it by hitting up the read link below. And, yes, Bob does plan to build a Bat Pod next.
