Well the Jag has had its first real test this week, a 500+ mile trip in 2 days from the north east to the Cotswolds and back. The return journey being with my 90 year old Mum in the passenger seat.
Overall, I am pretty pleased with the experience. Performance from the 2.5 petrol engine is more than adequate, and the economy was better than anticipated: travelling at legal speeds over the journey the return according to the computer was in excess of 36mpg which came as a big surprise. It seems to be a car that really benefits from good use of the cruise control on a journey that allows it. Mum's verdict was that "it wasn't as comfortable as that other car, but that was special" referring to the V6 XM, and I have to agree, but it was definitely better than I expected.
Where the Jag really does score over the Citroen is in the fact that everything still seems to work...
In summary: I like the car more than I expected to. It just seems a bit ordinary, I am used to having the only example of a model in a car park (even my daily runabout a ZX is quite rare now) and I think there are another 3 or 4 X types on my estate of about 120 houses.
