Jaguar S-Type Advice

Ever since our family car was written off a few weeks ago, I've been working on deciding what to replace it with.

I've finally decided on a S-Type, but would welcome advice and feedback from anyone who's owned one or even is in the trade.

I know the pre-2004 cars have build and reliability issues, but the later cars are supposed to be quite good.

It would be good to hear which model you owned, engine size and what issues, if any, you have had.

Also, has anyone owned the 4.2 V8 model? Any issues and what's it like on fuel?

Thanks and much appreciated.
