Second-costliest: Batmobile from the TV show Batman
Price: $4.6 million
Some 12,000 people packed a 3-acre tent in Scottsdale, Ariz., last month to watch Barrett-Jackson auction off this car from iconic television show Batman.
Barrett-Jackson CEO Craig Jackson says the vehicle would have attracted an even higher price than the $4.6 million it sold for had the last two bidders not decided to flip a coin to decide who got the car."One of the men said he'd brought $10 million, but who knows at what point one of them would have said: 'This is crazy!'" Jackson says. The auctioneer believes the vehicle attracted such a lofty price because the Batmobile "was one of the stars of the show. It did things -- it was an integral part of Batman and Robin catching criminals." After all, the vehicle has all sorts of superhero gadgets, from a built-in "batphone" to two rear-mounted parachutes.
