3. Jaguar XJS
Introduced in the mid-70s, the XJS was a big step for the company. Under the long hood, there was the well-known 3.6-liter six-cylinder. However, you could opt for a 5.3-liter V12 engine, which was a better choice if you wanted the full GT experience.
The XJS was an extremely popular choice, especially in America where Jaguar sold the majority of 115,000 cars they made. Due to its elegance, power, and speed, the XJS remained in production for an incredible 21 years. And, it is still a respectable car in every way. So, it is no surprise that prices are rising each year.
