Warren Mosler has been responsible for some pretty crazy cars over the years including this, the Consulier GTP. It was introduced in 1985 and produced until 1993, at which time it was re-branded as the Mosler Intruder and later the Mosler Raptor, which had some styling differences.
The GTP featured a rear-mid-engined layout with a turbocharged 2.2-liter Chrysler inline-four that, in this car, produced somewhere between 190 and 200 horsepower. It also had a fiberglass and foam monocoque chassis and a carbon-Kevlar body.
Mecum says that 83 of these were built, and the GTP also had racing success in IMSA. This one could probably stand to get some period wheels on it, but otherwise it’s an interesting piece of America’s supercar past. Click here for more info.

Jean Rondeau was a racing driver that drove open-wheel and saloon cars before moving on to sports racing prototypes in 1976 when he joined the Inaltera team. Inaltera was a wallpaper company, an industry whose natural extension is prototype sports cars to contest Le Mans.
This example, the first of three built, was the team’s test car. It is powered by a 3.0-liter Cosworth V8. Though it did not compete at Le Mans in 1976, it would enter the race the following year. It’s competition history includes:
1977 24 Hours of Le Mans – 4th (3rd in Class), with Jean Rondeau and Jean Ragnotti
After that, Inaltera pulled out of motor racing. Rondeau ventured on, building similar cars under his own name. He would later become the only person to win Le Mans with a car bearing his own name.
This car went to Switzerland after the 1977 season along with the other two Inaltera chassis. The current owner acquired all three later that year and sold the other two, keeping this one. It is now offered with an estimate between $510,000-$625,000. Click here for more info and here for more from this sale.

The IMSA GT Championship was an American racing car series that lasted from 1971 through 1998. Its shining moment was from 1981 through 1992, when a category called GTP existed. It featured prototype sports cars from some big name manufacturers like Porsche, Jaguar, Toyota, and Nissan.
Nissan won the championship in 1989 and this was the follow-up car to the series winning GTP ZX-Turbo. It debuted in the middle of the 1990 season and the competition history for this chassis includes:
1992 IMSA Grand Prix of Mami – 1st (with Geoff Brabham)
1992 12 Hours of Sebring – 2nd (with Brabham, Derek Daly, Gary Brabham, and Arie Luyendyk)
1992 IMSA Road Atlanta – DNF (with Geoff Brabham)
Brabham crashed it at Road Atlanta and that was sort of it for this chassis. It was later comprehensively restored and is powered by a twin-turbo 3.0-liter V-6 capable of 750 horsepower. It’s eligible for historic racing in the U.S. and in Europe (against Group C racers from the same era). Works GTP cars don’t change hands publicly all that often, so this is an interesting opportunity to get one of the big ones. You can read more here and see more from Mecum here.

We’ve featured some of Dan Gurney’s Eagles – mostly open-wheel cars. Well here is a GTP prototype AAR Eagle. It’s powered by a turbocharged Toyota 2.1-liter straight-four making 700-750 horsepower, depending on configuration. AAR and Toyota teamed up in the 80s for sports car racing and the Eagle Mk III dominated the 1992 IMSA GTP season. Between 1991 and 1993, they won 21 of 27 races. This is chassis #004 and its major wins are:
1992 12 Hours of Sebring – 1st (with Juan Manuel Fangio II and Andy Wallace)
1993 12 Hours of Sebring – 1st (with Fangio II and Wallace)
It also had 12 other victories and has been owned by Fangio II since it stopped racing. It is being offered for sale for the first time and should sell for between $700,000-$1,000,000. Click here for more info.

March Engineering was founded in 1969. The name March comes from the names of its founders: Max Mosley, Alan Rees, Graham Coaker, and Robin Herd. They were an F1 team until they built an Indy Car in 1981. In 1983 they entered the arena of Group C prototype racing cars and the 83G you see here was part of that effort.
The car was designed by the now-very-famous Adrian Newey and it is powered by a 3.0-liter turbocharged flat-six making between 650 and 800 horsepower depending on configuration. In any case, it is fast. This car competed in the U.S. IMSA GTP championship. And, in 1983, it won it. The competition of this car includes:
1983 Charlotte 500km – 1st (with Al Holbert and Jim Trueman)
1983 Lime Rock IMSA GTP – 9th (with Holbert)
1983 Brainerd IMSA GTP – 1st (with Holbert and Trueman)
1983 Sears Point 3 Hours – 1st (with Holbert and Trueman)
1983 Portland 3 Hours – 1st (with Holbert)
1983 Mosport 6 Hours – 7th (with Holbert)
1983 Road America IMSA GTP – 15th (with Holbert)
1983 Pocono IMSA GTP – 36th, DNF (with Holbert)
1983 3 Hours of Daytona – 1st (with Holbert and Trueman)
1983 IMSA GTP Champhionship – 1st (with Holbert)

1984 12 Hours of Sebring – DNF (with van der Merwe, Martin, and Duxbury)
1984 Lime Rock IMSA GTP – 1st (with van der Merwe)
It raced more than that but I’m not running down every race in multiple IMSA seasons. The car’s racing career ended after 1986. In 2003 the car was restored and was acquired by the present owner in 2005. It’s been used in several historic events including the Rennsport Reunion in 2004 and has been repainted to its 24 Hours of Daytona-winning livery. You can buy it for between $750,000-$1,000,000.
