The under two-liter Grand Touring (GT) cars have always had a place to compete within the ever changing regulations of international motorsports; the World Sports Car Championship from 1953-1961, the Speedworld Challenge in 1962-1963, the International Championship of Makes from 1964-1971 and the World Championship of Makes from 1972-1981. This included racing in the great endurance races such as the 24 Hours of Le Mans, the 1000-kilometer rounds at the Nürburgring, Spa and Monza, and the Targa Florio. Not to mention national races throughout Europe and SCCA races throughout the U.S. Alfa Romeo, Lotus, Porsche, Triumph all designed very lightweight successful competition cars. Abarth, an Italian specialty tuner, modified small-bore GT cars from Fiat and Simca, all with great success. These under two-liter GT cars filled up the racing grids on both sides of the Atlantic and provided some exciting automobile racing.
Today, under two-liter GT cars qualify to race in many great historic events worldwide, from the Rolex Monterey Motorsports Reunion to the Tour (de France) Auto because they are dual-purpose race and street cars. Due to their technology, great designs, eligibility and low production numbers, legitimate GT competition cars have steadily been increasing in value.
The value today of an under two-liter GT car is determined by many factors, including the car still having its unique competition features available on a race version that were not available on a production version, the quality of restoration and a good provenance.

1964 Porsche 904GTS
Following its success with the 718 series, aluminum-bodied Spyders during the 1950s, the 904GTS was Porsche’s first fiberglass sports car. One hundred were necessary to be built for homologation into the Grand Touring category. It had a steel chassis, to which the fiberglass body was bonded. The engine was a 2.0-liter version of the 4-cylinder, 4-camshaft type-587 Carrera engine. A new 5-speed, type-904 transmission was used. Suspension was fully independent with four-wheel disc brakes. Ten cars were retained by the factory, and these cars used the type-771, 8-cylinder engine and the new type-901, 6-cylinder engine. The 904 was very popular, so a second series of 20 cars was built with slight improvements.
It should also be noted that the factory built 12 cars with numbers 906-001 to 906-012. These cars used the 904 frame, but with the 6-cylinder engine. Also, some were specially constructed Hill Climb Spyders. The 904 was the beginning of a series of lightweight fiberglass cars from Porsche. Today, the 904 is immensely popular, as it is a true dual-purpose sports and racing car eligible for so many events.
AC Bristol Roadster
AC cars, or AC Autocars, was established in 1904 in South London, England by engineer John Weller. The AC name was taken from the AC Autocarrier three-wheeler, the company produced. AC built a variety of different cars, but in 1954, created a beautiful aluminum-bodied two-seat roadster called the AC Ace and later Bristol Roadster. It had a tubular chassis and was powered by a 2.0-liter, 6-cylinder engine. Interestingly, the engine was a derivative of the BMW 328 pre-war design. All told, 686 AC Ace Roadsters were built until 1962. In 1956, the Bristol-powered version was introduced. These were stunning cars to look at with their hand-formed bodies and wire wheels.

Regional Variances
The prices stated in this guide are based on U.S. values. The values of historic racing cars can vary as much as 25%-35% in other countries, depending on local market appeal, currency rates, import duties, and VAT. Most of the time, we are able to document known sales or closed escrows, as they say in real estate. When this is not possible, a logical estimate of the car’s value is given, based on its sales history and relationship to cars of its type.
