The NFT went up for sale on June 20, with bidding scheduled to last for four days, and a starting bid of 206 ETH (around $240,000). Apparently collectors decided the NFT wasn't enough to justify dropping that kind of cash on a car that is expected to sell for around $90,000, because the auction received no bids.
SuperRare, the marketplace used for the auction, explained that users must have missed the opportunity to bid "due to the craziness of NFT NYC" (a cryptocurrency conference that ran from June 20–23), and the project extended the bidding time by 24 hours. After the 24 hours had elapsed, they still had zero bids.
