The Lamborghini Aventador was made by New Zealand YouTuber David Jones.
The winning bidder is based in Christchurch and Jones was now working out how to carefully ship it to him.
The unique auction on TradeMe attracted 132 bids, 4054 watchers and closed last night. All money raised will be donated to Starship children's hospital.
The DIY project took two-and-a-half weeks to build, including one week to complete the cardboard body and one-and-a-half weeks to create the "driving skeleton".
Jones decided to build his own because he couldn't afford a real one.
According to the Trade Me listing, the car was being sold because it took up too much room.
It was made using an old TV box and cardboard from Warehouse Stationery.
"Selling because we don't have enough space in the garage and thought rather than throwing it in the trash, why not see if we can't raise some money for Starship!"
The new owner also gets an original owner's handbook, a cardborghini poster alongside an official unopened cardborghini repair kit.
But be warned: it's not in perfect condition as it's a bit floppy in places, has cracks in the windshield and a missing driver's side window.
