Shelby TurbineThe tank fittings can lead to the wrong story
Shelby Turbine has fittings underneath for accessories that never became ordinary retail equipment. Those details are interesting on their own; they do not make every loose car with added tanks a development sample.

Start with the cockpit and wheels
The Hong Kong-made Shelby Turbine entered the Grand Prix series in 1969. Production examples have blue glazing and black, champagne or white interiors. Documented white-interior production cars are red.
Bearing and capped wheels both occur, including mixed arrangements. Photograph all four wheel faces and the axles before deciding that a mismatch is either a factory combination or a later swap. A single side view cannot answer that question.
What the underside fittings actually tell you
A rectangular base opening and a circular rear projection were intended to accommodate developed fuel tanks. The tanks did not reach ordinary retail release, and reproductions are widespread.
Those fittings show how an accessory could attach. They do not authenticate the accessory. Ask for its history and close photographs, without forcing it onto the car to prove that it fits.
Likewise, clear glazing alone is not enough to call a car a prototype. Replacement parts can change the appearance of an otherwise ordinary example.
Decals and packaging are separate pieces of the purchase
Grand Prix cards included a button and buyer-applied waterslide decals. Shelby Turbine also appeared in the Indy Team four-pack.
List what remains with the car: applied graphics, a loose sheet, a button or original packaging. Check the low nose for chips and the windscreen for cracks before allowing a tidy presentation to stand in for a condition description.
