I could not agree more with Dennis. If you do not know that all the typical XJ40 issues have already been overcome then prepare either to try to live with them when they appear or fix/have them fixed. I have done a lot to my XJ40 during the last year (Project description), and it has not been expensive even if I live in a distant country. You guys in the North America have lots of cheap parts available in eBay, for example. I even found an AC condenser listed in Walmart, whereas I found only one seller in Europe, albeit the price was not high.
