It is totally possible to find a decent 4 wheel drive Trooper for under $1,000. Just make sure you don’t buy the 4 cylinder diesel or gasoline model, because performance was terrible. GM inserted the V6 from their small truck line, and all was well for the boxy looking sport utility. The 4 wheel drive system is quite capable, and many have successfully taken them up and over some huge rocks. They aren’t as abundant as some of the other best 4X4s on this list, but are plentiful enough to get one in good shape.
