Everyone remembers their first car - but when the motor in question is the first ever Batmobile, it takes some beating.
Fans of the caped crusader will be more than familiar with this glorious piece of car history, with its unmissable black bodywork and iconic red trim.
Now the legendary car used by Batman and Robin in the Sixties film and TV series is up for auction - and you'll need a Bruce Wayne-sized bank balance to snap it up.
U.S. car customiser George Barris, who transformed the Lincoln Futura into Batman's faithful runaround, has decided to sell the superhero's company car.
It will be auctioned off by Barrett Jackson on January 19 at its sale in Scottsdale, Arizona, where Mr Barris has branded it 'the most valuable car in the world'.
Both parties expect the 19ft-long piece of automotive history will sell for 'multiple millions'.
Batman and Robin inside the iconic Sixties motor (SWNS)The Batmobile started out as a 1955 Lincoln Futura which Barris, 87, bought from Ford in 1965 for a nominal $1.
He then spent 15 days and $15,000 transforming the concept car into the one-of-a-kind Batmobile to be driven by actor Adam West.
It may not be quite as advanced as Christian Bale's techno Batmobile in The Dark Knight, but for petrolheads and film fans the original Batmobile is just as iconic.
George said: "I think it is the most valuable car in the world and the public really get a kick out of it when they see it.
Interior: Inside, the Batmobile looks like a comfy ride (SWNS)"I designed and built the Batmobile and I have shown it all around the world but now I think it is time that someone else can enjoy it.
"Over the years I have built many cars and I always get attached to them and it will be sad to see it go but I would like someone else to enjoy it now.
"When I created it I wanted to make it a star like Adam West and Burt Ward. It was not just a car."
The Batmobile uses a V8 engine and automatic gearbox but it is its unmistakable design and famous history which will appeal to collectors.
And if it sells for the $2 million Barrett Jackson hopes, it will rank among TV and film’s most valuable cars.
The Aston Martin DB5 driven by Sean Connery’s James Bond in Goldfinger sold at a London auction in 2010 for $2.6 million while the Ford GT40 used by Steve McQueen in 1971 film Le Mans fetched $6.5 million earlier this year.
The Batmobile used in the Dark Knight is a far cry from its Sixties cousin (PA)Craig Jackson, chairman and CEO of Barrett-Jackson, said: "The Batmobile is true Americana and it’s hard to put a dollar figure on something like that.
"The difference is that this is the real deal, the original and the only one to have been on the Batman series - it’s been in George Barris’ garage for all these years and that is invaluable.
"This vehicle not only marks the significant Bat logo that sits on the middle of its door, but a time in television history where they defied the odds of making a car the real star of the show.
"It revolutionised an entire industry that followed in its footsteps and we couldn’t be prouder to have it cross our block in Scottsdale as it goes up for sale for the very first time."
