9. Jaguar XJ6
When they introduced the XJ6 in 1968, there was nothing similar to it on the market. The XJ6 was a sleek, elegant sedan. They equipped it with powerful straight-six engines and even offered a 5.3-liter V12 for the most demanding customers. This was the first car that was the perfect blend of luxury with a sports appeal (via Autozine).
Also, its signature shape lasted all the way up to 2009 through eight different generations. In all of its iterations, the Jaguar XJ6 was always a popular luxury car in America. And that means there are plenty of those around. Some of the early models are quite affordable, so this could be the perfect starter classic if you’re into legendary British motors.
