The Vauxhall/Opel Calibra, produced from 1990 to 1998, was a stylish and sporty coupe that captured the hearts of car enthusiasts across Europe. This model, specifically targeting the "G to S registration" period (which likely refers to UK registration plates issued from 1998 to 2001), represents the later years of the Calibra's production run. The Calibra's sleek, aerodynamic design, with its low-slung profile and rounded lines, was a departure from the boxy styling of many cars at the time. It was a car that emphasized both performance and aesthetics, offering a blend of sharp handling, powerful engine options, and a luxurious interior. The Calibra's success was further solidified by its available engine choices, which included the peppy 2.0-liter 16-valve and the more powerful 2.0-liter turbocharged engine. The latter variant, capable of reaching 150 mph, was particularly lauded for its performance, making the Calibra a real contender in the sporty coupe market.

The Vauxhall/Opel Calibra proved to be a popular choice amongst those seeking a stylish and engaging driving experience. However, the car's production came to an end in 1998, making it a collectible and sought-after model for those who appreciate its unique blend of style, performance, and practicality. The "G to S registration" period, likely encompassing the later years of the Calibra's production, further emphasizes the car's heritage as a classic of the late 1990s. Today, the Calibra remains a testament to Vauxhall/Opel's commitment to building exciting and desirable automobiles, appealing to those who crave a touch of nostalgia and performance in their driving experience.
