Thinking of buying an Isuzu Bighorn/Trooper as a bit of a "modern classic" 4x4/offroad vehicle?
Check out this very comprehensive buyer's guide for the Isuzu Trooper.
It goes into great detail about all the ins and outs of finding, inspecting and buying a good example of the Trooper.
NB: This guide is focused on the second generation Trooper only, not the first - hopefully they will do a first generation buying guide at some stage as well.
