Marty! Time is running out to buy a replica DeLorean from the last Back To The Future theme park ride in the world! Although it’s not going for cheap.

It’s a bittersweet day for fans of the Back To The Future franchise, as the last remaining Universal Studios ride based on the film trilogy is scheduled to close on May 31st. The Universal Studios locations in America closed their Back To The Future rides back in the early 2000s, but Universal Studios Japan had kept theirs ticking. But while the ride will no longer be taking fans to back in time at 88 mph, the theme park is auctioning off pieces of the ride to the highest bidder.

One of the initial artifacts that has gone up for sale is the full-size replica of the iconic DeLorean time machine that sat outside of the ride, and if the initial bids are any indication, it’s worth more than its weight in Libyan plutonium. According to the Japan Times, the non-functioning car was put up for auction on Sunday night via Yahoo Auctions, and someone has already placed a bid for ¥9,999,999,999, the maximum amount allowable on the site. The bid, which equates to about $91 million, may be nothing more than a troll worthy of Biff Tannen himself, but Universal Studios Japan is looking into the offer.

Whether or not the massive bid is real, when the car does finally sell, the proceeds from it and anything else from the ride will be donated to the Michael J. Fox Foundation for Parkinson’s Research.
