Hi Dude.
I'm in Inverness area too. Just got a RR P38. Not the best one out there. But it goes, sometimes. Had a couple of Discos. One sorted for offroading, lift, big tyres, high arches, etc. Loads of fun. Someone suggested a 90 which are great but hold their price. You could get a really cheap Disco to start. Easy to work on if you have to (which you will cos it's a landrover) and loads of parts & mods available.
Geez a shout if you wanna go offroading. Better with more vehicles if you get stuck. Needing new tyre first tho.
You could always try the 4x4 experience at Farr. Some of the guys at my work go there. Not been myself yet tho. Use theirs or take ur own. You could try a disco there.
I'm rambling but it's just me putting off fixing my RR electrical problem. Bloody RR's.
Cheers Dude.
