The Turbofire is one of the four fully Mattel designed concept cars released in the 1969 product line.
All previous concept cars had been based on existing full sized custom show cars.
The other three, also designed by Ira Gilford, are the Twinmill, Splittin' Image and the Torero.
Although first issued in 1969, the Turbofire was produced for several years and as such is one of the most common redines.

Among production Turbofires, the dark interior has only been found in red cars.

White vs. Dark Interior

About 1% of red Turbofires have the dark interior.
All production Turbofires have clear glass.

Wheel Variations

Over 95% of all Turbofires were assembled with bearing type wheels.
Capped wheels can be found but they are not common.
Some Turbofires have a mixture of bearing wheels and capped wheels.

Although the wheel type presents opportunities for unusual variations, it has no particular influence on the value of a Turbofire.

Paint Colors
The Turbofire came in all of the spectraflame colors and a multitude of shades.
The tail light is usually painted in an opaque international orange color, however certain colors have no tail light paint at all.
See the chart at the end for color rarities.

Painted and unpainted tail lights

One interesting peculiarity is that some light green Turbofires have faded to the point where they appear to be unpainted.

However, a close inspection of the inside of the fenderwells will reveal some tell tale remnants of the light green paint.

Traces of light green paint

Two complete preproduction Turbofires are known.
The purple is handpainted, coming from the famous Room 1111 at Irvine. The gold one turned up on eBay in 2003.

Purple and Gold Prototypes

The preproduction cars have a casting variation which clearly distinguishes them from the production casting.

Prototype vs. Production Hoods and Engine Compartments

On the preproduction piece, the rear lid opens wide and the engine exhaust pipes extend to the rear of the base.
Similar to early Ford J cars, there is no travel stop, so the hood could be extended backwards too far and could easily be broken off.

On the production piece, the travel stop was added to the base, on top of the tail pipes.
The peg on the hood was added and and the hinge was redesigned, adding metal to strengthen it.

The Turbofire casting was reproduced by the Muky toy company in Argentina.
They issued a bunch of variations of the Turbofire under the name of ??
