Overall Rating
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.
Initially, the Astra was available in hatchback, saloon, and estate forms. A panel van and a convertible also appeared in the early 1990s. These body styles were later followed by a coupé in 2004, and the sporty Astra OPC appeared in 2005. The Twin Top retractable hardtop convertible replaced the soft top convertible in 2006, while the Caravan was renamed to Astra Sports Tourer since 2009....(Read more on Wikipedia)
