If we're deciding that Sovereign is more correct than "XJ6 Sovereign" than yes. So you can do this without manually changing each one? I'm just wondering if we should wait for a few more people to weigh in on this, or I could ask this question on a Jaguar enthusiasts forum. But to me it's really looking like this is what it should be.

I mean really it's not exactly a totally seperate model (neither are the Daimlers), it's just a naming system, but then Bentley there was the Mulsanne, Eight, Turbo R and Brooklands and they were all the same basic design.
