Mark Racop spends his days creating incredibly accurate, drivable replicas of the Batmobile from the 1966 Batman movie and series. Officially licensed and lovingly detailed, they're the ultimate object of lust for old-school Batman fans.
If you're not quite ready to drive your own Batmobile along, you can grab "Bat Parts" for your own car to give it a bit more of a Dark Knight feel. But for the whole car, you'll be looking to spend around $150,000. Still, it seems sort of worth it, right?
