Are Jaguar car parts expensive?

Are Jaguar car parts expensive?
I realise it's all relative, but I'm a little confused as to whether the parts for a 2004 X-Type would be expensive or not. I'm comparing it to a Renault Laguna II of a similar age and I'm wondering whether Jaguar (which I believe is now owned by Ford) could really be pricier for parts than a French car?
