Reddit user listrophy posed a question yesterday asking: “What’s the largest item you can have shipped from Amazon? Because I think my neighbor just got it.” They linked a picture of a flatbed truck with a massive package bearing Amazon’s iconic logo, complete with the company’s usual packaging tape.

Still, the photo was met with skepticism. Users said it was Photoshopped. And Jerry Seinfeld, in the course of his “Ask Me Anything” Q&A session even called foul on the photo. But Amazon says that it’s the real deal.

As it turns out, the box contains a new Nissan Versa Note, which was a part of a promotion that began in September of last year, reports Recode.net.

As a part of the deal, some purchasers got their cars delivered in a massive Amazon box, exactly as pictured.

It’s not clear exactly how the car gets out of the box once it’s delivered, though.
