1993 Vector Avtech WX-3R Roadster Prototype

Offered by RM Sotheby’s | Phoenix, Arizona | January 17, 2019

A week ago we featured the coupe version of this car, the Vector Avtech WX-3. This is the topless form, the WX-3R Roadster. Nothing says over-the-top supercar quite like a rear-engined V-12 roadster with no roof, scissor doors, and headrests that appear to be taller than the ridiculously-raked windshield.

This car debuted alongside the coupe at Geneva in 1993 and is powered by a twin-turbo 6.0-liter V8 and a GM automatic transmission that could take this thing to over 200 mph. Series production never occurred, and this remains a one-off, fantastically 90s, supercar prototype. I literally had a poster of this car on my bedroom wall as a kid.

This is the first time this car has ever been for sale publicly, as it is being sold from company founder Jerry Wiegert‘s personal collection. It should bring between $450,000-$550,000. Click here for more info and here for more from this sale.

The First 275 GTB

1964 Ferrari 275 GTB Prototype

Offered by Gooding & Company | Scottsdale, Arizona | January 19, 2019

The Ferrari 250 series of cars went on sale in the early-1950s. Ferrari iterated on them for over a decade, but by 1964 they were pretty long-in-the-tooth. So when the 275 GTB was introduced, it was a revelation.

This was the first example they built, and it – like all of the other examples that followed – used technology brought about by Ferrari’s 275P Le Mans program. Power is from a 3.3-liter V-12 making 265 horsepower.

Ferrari kept the car through 1965, using it as a workhorse and revising it until they got it where they liked. Even the coachwork changed from its initial debut. It now wears a long-nose body style.

The car was entered by its first owner in the 1966 Monte Carlo Rally. Ferrari provided support, which is why this car is equipped with front rally lighting, three windshield wipers, and more. It’s had a string of known owners since and was acquired by the current collection in 1994.

It hasn’t been shown publicly in 25 years and is said to be in need of some serious service before use. Still, it should bring between $6,000,000-$8,000,000. Click here for more info and here for more from Gooding & Company.

If my schoolgirl-like giddiness for this car becomes too distracting in the text that follows, please just bear with me. I love Vectors. They are outrageous. The company traces its roots back to the 1970s when founder Gerald Wiegert showed his first prototype, the W2, in 1978. The W8 was their first production car in 1989.

The Avtech WX-3 debuted in 1992 and was to go into production with three engine options. This, the coupe version (just wait until next week), is finished in a beautiful shade of Brilliant Aquamarine, though it was originally silver.

Wiegert lost control of the company shortly after this car debuted and the new owners, while barred from using this design, more or less did anyway with the very similar-looking M12 that used Lamborghini engines. This car is powered by a twin-turbocharged 7.0-liter V8 putting out 1,000 horsepower.

This is the only car like it in the world, and Wiegert has never parted with it, until now. It’s so over-the-top in a wonderfully 90s kind of way. I just love these cars. The details are just so extreme, to wit: its shark-like appearance and the fact that the fuel cap looks like it was ripped right off of a Cessna. It is expected to bring between $450,000-$550,000.

Alfa 155 GTA Stradale

1993 Alfa Romeo 155 GTA Stradale Prototype

Offered by Bonhams | Padua, Italy | October 27, 2018

Photo – Bonhams

The Alfa Romeo 155 was Alfa’s “compact executive car” built between 1992 and 1998. In some trims, this was a downright good-looking car (and still is). They used it in DTM and various touring car series throughout Europe. After some victory in ’92, Alfa decided to build a road-going series of 155 GTA Stradale cars like Mercedes and BMW had been doing for years.

Built by Abarth, the cars were to use a turbocharged 2.0-liter straight-four capable of 190 horsepower. It’s got 4-wheel-drive and an aero kit was added to make it appear boxier and more DTM-like. Company executives wanted a V6, and then they realized how expensive it would be to actually produce a run of these things…

So the project went nowhere. And this was the only example produced. First road-registered in Germany in the late 1990s, the car has accumulated 40k kilometers through a handful of owners. It’s pretty awesome and will cost a serious enthusiast between $210,000-$250,000 to purchase. Click here for more info and here for the rest of Bonhams’ Padua lineup.

Update: Withdrawn from sale.

Matra Jet Prototype

1967 Matra Jet 6 Prototype

Offered by Aguttes | Linas, France | September 30, 2018

Photo – Aguttes

The Djet was a product of the Rene Bonnet company but when they went bankrupt in 1964, Matra bought it out and continued production of the little sports car. They iterated on the cars, selling the Djet 5 and 5S. Eventually they dropped the “D” and the car became the Jet 5S.

And then came version 6. What we have here is a prototype that used a Jet 6 as the starting point and is now a purpose-built race car. It’s powered by a bored-out 2.0-liter Gordini straight-four from an Alpine.

It was raced by its original builder, Marcel Moissonnier, in hill climbs around France. The current owner acquired it in 2015 and has used it on closed-circuit tracks. One-of-a-kind, it should bring between $17,000-$23,000. Click here for more info and here for more from this sale.

Update: Not sold.

Three Prototypes

Three Prototypes

Offered by Worldwide Auctioneers | Auburn, Indiana | September 1, 2018


2004 Ford GT Confirmation Prototype CP4

Photo – Worldwide Auctioneers

We’ve featured prototypes of the original Ford GT40, but here’s one of what we’ll call the “second coming” of the GT. The original concept car for this model debuted in 2002 and it’s thought that Ford built nine “confirmation prototypes” of which this is CP4, or vehicle #00007. Its purpose was to be the test bed for ride, steering, handling, and climate control systems.

All black, it was the first GT to hit 200 mph. It’s powered by a 5.4-liter supercharged V-8 making 550 horsepower. It joined the collection it is being sold from in 2012 and it is street legal. It’s the only “CP car” from the GT program that is road-registered and not governed to 15 mph. It’s thought that only four GT prototypes remain and this one is selling at no reserve. Click here for more info.

Update: Sold $467,500.


1997 Ford Ghia Vivace Concept

Photo – Worldwide Auctioneers

Well here’s a weird one. It looks like the love child of a Ford Ka and a last-gen Mercury Cougar (it’s actually based on a Mondeo platform aka the Ford Contour). It’s honestly pretty crazy this car still exists at all. It’s just a rolling concept car – there’s no engine, no interior. It’s just a two-door coupe body with some wheels on a chassis.

Ford and Ghia teamed up for two concept cars in 1997 just to explore new shapes and using aluminium space-frame construction. The body is fiberglass, the wheels don’t steer, and the doors don’t even open. It’s like having a rolling brick. Not much to do with it other than look at it. But hey, at the same time, you’re going to be the only person who has one. Click here for more info.

Update: Sold $1,650.


1960 Seagrave Prototype

Photo – Worldwide Auctioneers

In 1960, the Seagrave Fire Apparatus, the longest-running producer of fire apparatus in the United States dating back to 1881, decided they wanted to build passenger cars. But not just normal American passenger cars, but economy cars. This in 1960, when American automobiles were perhaps approaching their largest.

This two-door hardtop is much smaller than the photo above makes it look and it weighed in at only 1,700 pounds. Seagrave managed to build three prototypes (two in fiberglass, one in aluminium), and this fiberglass example was powered by a 2.7-liter Continental straight-four engine capable of 65 horsepower. It was pulled out of a barn in Michigan in 2013 and is restoration ready. It’s one of the most interesting cars for sale in Auburn this year.

Update: Sold $11,000.

Aston Martin DP215

1963 Aston Martin DP215 Grand Touring Competition Prototype

Offered by RM Sotheby’s | Monterey, California | August 24-25, 2018

How do you make an Aston Martin DB4GT look downright pedestrian? Well the DB4GT is one of the most sought-after competition Astons… so you’ll have to show up with something pretty intense. Well how about this DP215? It’s the only one the factory made and they built it exclusively for Le Mans.

Aston returned to works sports car racing in 1962 with the DP212, or Design Project 212. It had some aerodynamic issues (like you know, wanting to take off at high speed) and they evolved the car from there. A pair of DP214s raced the 1963 sports car season and the DP215 was the ultimate evolution. It’s a one-off car built to show what Aston’s engineers were capable of. Aerodynamic and with a Kamm tail, this car was extremely fast, hitting just a tick over 198 mph on the Mulsanne Straight.

It’s powered by a 4.0-liter straight-six with aluminium heads that’s good for 323 horsepower. Driven by Phil Hill and Lucien Bianchi at the 1963 24 Hours of Le Mans, this car was 12 seconds a lap faster than a 250 GTO. It ultimately retired due to gearbox failure.

Aston held on to the car until the 1970s, even after selling all of the other DP cars. The engine was separated and wasn’t reunited with the car until about 15 years ago. It’s been expertly restored and it’s been used. As a one-of-one Aston works racer, it’ll bring big money. The proof is that you need to be pre-approved by RM Sotheby’s to even bid on this car.

Update: Sold $21,455,000.

Marcos TS500

2003 Marcos TS500

Offered by Coys | Fontwell House, U.K. | July 12, 2018

Photo – Coys

Marcos Engineering lasted quite a while, from 1959 through 2007. Over the course of that time, they made a number of different models in varying quantities and each successive car looked like an evolution of the design before it (with one major exception). For example, compare the overall look of this TS500 to 1970’s Marcos 3-Litre.

The TS500 was an updated version of the company’s Marcasite TS250. Instead of a 2.5-liter V-6, the TS500 features a 320 horsepower, 5.0-liter Rover V-8. Sixty mph arrived in about four seconds and the car tops out around 160 mph.

Only a handful of these were made before Marcos switched up production to focus on the TSO before ultimately going out of business. This car was the original factory prototype and press car. It’s a 15,000 mile car with service records. A rare treat from a lost British sports car manufacturer, this convertible should bring between $33,000-$40,000.

Two Shelby Prototypes

Two Shelby Prototypes

Offered by Bonhams | Greenwich, Connecticut | June 3, 2018


1997 Shelby Aurora V-8 Can-Am

Photo – Bonhams

The Shelby Can-Am was a racing series that used purpose-built race cars from Carroll Shelby. All cars were identical and powered by 255 horsepower V-6 engines. The series – which was open to amateurs – ran from 1991 through 1996 in the U.S.

Originally, Shelby wanted to offer a bigger, badder version of the car. He only built one prototype – and this is it. It’s powered by the then-popular 4.0-liter Oldsmobile Aurora V-8. It was tuned to make 500 horsepower and was the same engine used in the Series 1 sports car. This is the only example built and it ran some test laps at Willow Springs but otherwise has been sitting in Ol’ Shel’s personal collection since. This would be a fun track day toy for someone and it should cost them between $20,000-$25,000. Click here for more info.

Update: Sold $100,800.


1983 Dodge Shelby Ram Prototype

Photo – Bonhams

The first generation of the Dodge Ram was produced from 1981 through 1993. The beginning of production coincided time-wise with Chrysler’s relationship with Carroll Shelby. You might think it’s weird to have Shelby’s name on a truck, but hey, he built a Dakota and a Durango.

This one-off Ram was partly a styling exercise (to mimic the styling of the recently introduced Shelby Charger). But because Shelby couldn’t help himself, the motor was spruced up as well: it’s a 300 horsepower, 5.9-liter V-8. It’s a pretty decked out truck all around. This is coming from Carroll’s personal collection where he maintained this 11,000 mile truck since new. It should sell for between $10,000-$15,000. Click here for more info and here for more from this sale.

Update: Sold $33,040.

Porsche 914/6 Murene Prototype

1969 Porsche 914/6 Murene by Heuliez

Offered by Osenat | Strasbourg, France | May 1, 2018

Photo – Osenat

The Porsche 914 was a sports car designed in collaboration with Volkswagen. It went on sale in 1969 and was built through 1976. It’s mid-engined and came with a flat-four or a flat-six in 914/6 configuration.

This car is unlike any other 914. First of all, it’s a closed coupe and not a targa, as the 914 was from the factory. It was designed by Jacques Cooper (who also designed the original French TGV high-speed train) and he took the design to Heuliez who had a car mocked up and then built.

It debuted at the 1970 Paris Motor Show and still used a 2.0-liter flat-six that makes 109 horsepower. Porsche was working with Karmann to build the cars and didn’t want to split the duties between two coachbuilders. Heuliez bought the car from the firm that Cooper was working for when he designed it and kept it until 2012 when they liquidated most of their collection. Since its recent acquisition, the new owner went through the car mechanically and made it fit to drive. It’s a one-off, coachbuilt Porsche Prototype and it should bring between $225,000-$275,000.
