Newbie here, looking at buying my first Jag and the S Type R version has got my eye at the moment. Just wondering how hard/easy it is to change the dashboard trim on these. I've seen a few nice models but with a silver/aluminium dash both we really prefer the wooden dash look, are they easy to swap over ? Also, any tips/advice on what to look out for when buying an R model are welcome. I've done a little bit of reading up so far and want a post 2004 model, but any tips are welcome. Ta
