Opel Astra:

The Opel Astra is a compact car/small family car developed and produced by the German automaker Opel since 1991, currently at its sixth generation. It was first launched in September 1991 as a direct replacement to the Opel Kadett. As of 2025, the car slots between the smaller Corsa supermini and the larger Frontera subcompact crossover SUV.
