The owner of a real-life Back to the Future hoverboard is selling his prized possession on Trade Me to aid charity - if you've got a spare $700,000 to start the bidding.
Seller 'j_22' is Aucklander Jamie Vujcich, who bought two of the original Hendo Hoverboards and appears in one of the photos on the listing.
The hoverboards were first released on October 21, 2015 - the famous date that Michael J Fox's character Marty McFly travelled to in the movie sequel in order to save his child.
There were only 11 made in total and Vujcich bought two, importing them from the US at a cost of around NZ$15,000 each.
The listing references a video from Vujcich's YouTube channel and mentions media articles and events where he was showing his original purchases. Vujcich confirmed to Newshub he had listed the "amazing piece of tech" on Trade Me.
"It's now time for me to part with my dream and my most prized material item, and let someone else take the opportunity to enjoy the Hendo Hoverboard as their own," Vujcich says.
"My main motivation for selling this fantastic and unique piece of tech is to be in a financial position to be able to help an existing and potentially start-up my own charity," he told Newshub.
"Also I'm not using it and it would be great for someone to be able to bring it to life again."
The listing says Vujcich wants to help out Mike King's charity funding as well as starting a charitable organisation of his own to "help support the kids of our country when it comes to issues like depression, hope lost and so on".
Only two now exist in the world and the other remains with Arx Pax Hendo, the company that made them, in the USA, Vujcich told Newshub.
"Two's better than one, and I have a passion for the technology," Vujcich told Newshub back in 2015. "I love it."
It's not clear what happened to the other hoverboards or the second one that Vujcich purchased, but it's that rarity of a working hoverboard that has the bidding starting at NZ$700,000, with a buy now price of NZ$998,000.
At the end of the original movie, Christopher Lloyd's Doc Brown utters the phrase "Roads? Where we’re going, we don’t need roads."
Well, neither does the hoverboard; although it does require a somewhat specialist surface to work. It uses a proprietary magnetic field architecture to lift the board off an aluminium or copper sheet surface.
Vujcich describes the hoverboard as a "solid investment", a "real conversation piece" and a "truly innovative and unique item".
"Not only is this a technological work of art, it is fully practical and scalable as well for a robotics business idea."
Vujcich's hoverboard was also ridden by legendary pro-skateboarder Tony Hawk.
Whoever forks out the money required to secure the rare hoverboard is also going to have to buy new batteries - the current ones are too old, so new lithium polymer batteries will be a priority if the buyer wants to fly.
For fans of hoverboards or the Back to the Future movies, Vujcich is auctioning another related item that won't break the bank.
The personalised plate LEVAT8 is also for sale, starting at a much lower $1800 and with a buy now of $2200.
