If you really want the 4×4 side of things then IME and 03-05 Freelander. Alright, they still sound agricultural and plenty of people will say bad things about them. But I've lived with an 03 (from new) for 3 years and it never went wrong, a 55 (from new) for 6 months and it never went wrong, and an 06 (from 08) and it never went wrong. Only had a couple of minor niggles but nothing mechanical/engine/transmission/ECU related at all.
If you get a good one then you'll be sorted – just do your research and/or get an inspection if you feel the need.
IMO I wouldn't recommend spending £6k on a RR of Disco, unless you know someone that has a peach.
Plenty of other options our there too.
PS a friend bought a 54 XC90 last year and had to replace the engine within 3 months – he was not chuffed. Another friend also had nothing but problems – engine and electrical from new on an 04. Not saying avoid XC90 – just saying BEWARE whatever you go for.
