Im in a "similar" positiont to you...... (well same age same budget.. and want either an XE or an Xf!).
I used to have a lovely 2.2. Auto Diesel X type...stupildly I sold it though!
This time around, I want a petrol, as I wont be doing many miles at all, as Im recently retired.
I did even have a look around for an 09 or 09 plate petrol X Type...could only find one though! That wasnt a diesel though, that was an 08 diesel estate.
Saying that...maybe they stopped production on 2008?
As regards to an XJ......Id love one! Only trouble is...Im no mechanic...and I feel (probably wrongly!) that it wouldnt be something for me...as I say...Im probalby way off! I mean if I was to find a "sorted" XJ....with the mileage I would do....it would probably be ideal! (I intend...as soon as covid i gone! to spend the winters away..so I would only be home for maybe 7 months of the year anyway!).
Decisions , decisions...Sorry Im no use to your questions........Still at least you arent the only one in this decision making process!
I did have a quick look online at Jaguar cars on their site...........in all fairness....they werent as expensive ( compared to other sellers I mean!) as I thought they would be...so could well be an option, as you would surely get a good a car from them?.
