Thanks happygu - it did apparently have some sort of lift kit fitted and the guy thinks it's a 2" lift but is not sure of the details. I think I will definitely take your advice and apply a bit of patience and check a few more out before committing.

I did see that this one had a switch for the diff locks - is it just for the rear diff lock or for all of them?? Which of the diffs can you lock (transfer case?, rear?, front?)
