XJ Purchase Advice

I’m starting the hunt for an XJ, and am considering all models, all years (with a preference for British Racing Green, wow that color looks great on this car).

I’d prefer to avoid New England cars (road salt aplenty), and am looking at XJs in Florida, Texas, even California.

Any recommendations for a service that would be willing to check out a car for me, given that most of these cars are too distant for me to examine personally? Any other advice on purchasing a distant XJ?

I love the idea of the 5.0 liter supercharged engine in the XJR. If any of you have one of these, do you use it as a daily driver and what would you say are the pros and cons?

Thanks in advance for any insight.
