These Are Some Of The Rarest Prototypes To Ever Hit Auction

A two-seat Mustang, a GT racing F40 prototype and more!

The automotive world is all about one-upping the competition. Yeah, you have a Mustang but is it a 5.0-liter V8? That Aventador is nice but an SV would be just a bit nicer. The logical extreme is prototypes, especially prototypes of famous cars or iconic models. The idea is that while six people may own a Koenigsegg One:1, only one person owns the original development model. In the spirit of exclusivity we’ve rounded up some of history's rarest prototypes that managed to somehow hit the auction block.

Only 275 Jaguar XJ220s were ever made, which makes Jag’s ill-fated supercar pretty damn rare on its own. Much rarer however are the XJ220 prototypes, of which only five were made. This red example is prototype #002. It measured 7” inches shorter, 5.9” narrower and was lighter by 397 pounds than the production model. As for its engine, well it’s a twin-turbo with displacement rated between 3.2 and 3.5 liters. Mystery engine aside, XJ220 prototype #002 apparently hit 186 mph during testing! It ended up selling at auction for just over $100,000 back in 2013 which may go down in history as a giant bargain.

The McLaren 675LT is a relatively new supercar, but the automaker was apparently in a big hurry to offload its prototypes. Only five were made and one was recently listed for sale at a hair under $400k ($399,172). That’s actually not a bad price, especially considering the 675LT was $349,500 at launch. Unlike the Jag, this prototype isn’t a frankencar. It was rebuilt to be sold and has just 28 miles on the clock. There is a small sticker that reads “VP433” which means “Verification Prototype.” Other than that it’s good to go.

Now a prototype of a production car is cool, but what’s cooler is a prototype of a car that never made production. That’s what we have here in the form of the Shorty Mustang. This two-seat ‘Stang was actually built by a company called Dearborn Steel Tubing for Ford. While the front came from a 1965 Mustang the fiberglass rear was custom. Unfortunately Ford decided to crush the two-seater but before it could do so Shorty’s chief designer stole it. The Mustang was put into hiding and changed hands a few times before it was sold by Auctions America in March 2015 for a staggering $511,500.

It might not look like it, but underneath this racing livery is a Ferrari F40 prototype. Only eight of these were made and this one was actually shown at the 1987 Frankfurt Motor Show. This prototype wears a racing livery because it actually competed in GT racing. As such it packs a beefier engine—600 horsepower—along with bigger brakes, larger wheels and tires and other weight-cutting bits. It was put up for sale by RM Auctions with bids expected to come in between $900,000 and $1.2 million. We can’t find its sale price so we don’t actually know how much it ended up going for.

You didn’t think we’d forget about the Koenigsegg One:1 did you? Only seven of these were made, with one car used for auto shows and to set a ton of world records. Now it's up for sale. How much? Try $6 million. To be fair the dealer says this car is coming with a full factory refresh and it is probably one of the most, if not the most, capable supercar on the planet in the right hands. It's also basically a museum piece that you can take to the track...if you dare.
