Hi Forum, I'm in the market for an S type after coming away from an E60 5 series, I've looked around for buying advice but not found anything specific. I have about £3500 to spend give or take a few hundred quid. Must be auto and preferably with nav, a sport version would be nice. Need to get 40 m.p.g on a run but no preference as yet between diesel or petrol, though will prefer the most reliable of the two. So if you'd be able to guide me with regards to which models, years and engines to avoid and problems to look out for I'd be very grateful, thanks.
