For what it's worth, I just purchased my 2002 DMAX a couple days ago, it just had all the injectors replaced for the first time, and it has 235,000 on it. I just love the truck, it runs great, rides great (comfortable and roomy), has plenty of power, and it's basically bone stock (except for little bigger tires and exhaust), so I know it could have a lot more power too. I just searched around, a LOT, and bought the one that I thought was the best "bang for my buck", and that was in the price range I was looking for. Every make, and model truck has it's "quircks", but just listen to the experts here, they know what their talking about, and helped me out IMMENSLY, then just make the choice that's right for you. Welcome, and good luck on your search!
