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 G2 Preludes are quite rare – though they do have a lot of detail that were phased out of the later generations. The red one and white one is in the collection with their respective G-26 labeled boxes (depicting a red car). The hood hinges in front as in the actual car – revealing an engine finished in chrome. The moonroof, hood, trunk and doors all operate.
