Diapet has modeled the G1, G3 and G4 Preludes over the years in 1:40. As typical with other Diapets, the Preludes focus on operating features rather than fine castings or details.
The G1 Preludes were available in a few colors. Of note are the fact that the trunk, hood, doors and even moonroof operate! The doors have windows that are half down with a finished door inside (a feature not found on later Diapet Preludes). The underside of the hood has the sectional details. The engine is finished in chrome. They come in a box depicting a bronze colored car.

The G1 Prelude here in yellow has a black interior.

Here is a gold version of the car.
