Start with what the Isuzu Gemini is: a 2-door coupé / 4-door sedan (car) / sedan with Petrol engine, built from 1974 to 2000, as the oil crises and the first emissions rules rewired the industry. What it meant takes a little longer.
Where it came from
The Isuzu Gemini (Japanese: いすゞ・ジェミニ) is a subcompact car produced by the Japanese automaker Isuzu from 1974 until 2000. The same basic product was built and/or sold under several other names, sometimes by General Motors brands, in various markets around the world. While the first generation was of a rear-wheel drive design, later versions were all front-wheel-drive, and the last two generations were no more than badge-engineered Honda Domani until the name was retired in 2000.
