Correct. I suspect the xjr you were looking at was a Jaguar company car as the reg is only a couple of digits off mine. Nothing wrong with the BM (I have owned a few) but the Jag is more refined.
Not sure of your budget but there is a good one for sale in the classifieds - Grey, £16k The owner is a mod on bmwcarmagazine.com He knows his stuff and made sure BMW sorted any minor niggle. It has also had a new warranty
