I guess it depends on the actual vehicle whether you spend an extra $1000. Being a 90 or 93, there both going to be used vehicles, so both are going to have different histories. If you looked at a 90 model bronco and it was ill treated and then went and saw a 93 and it was in better condition, of course you will pay the extra amount. It all depends on the actual vehicle. Shop around and see what you can find for the best value for your dollar.
