My wife and I just bought our Trooper w/ 133 k miles for 3K. The previous owner told me about the oil cooler o-rings leaking oil. Through the research I had done, I knew this was a common and easy to fix problem. Isuzu fixed the oil leak problem in 98, but it is very common in every year before that. ALL ISUZU'S USE LOTS OF OIL. It does not affect performance or longevity. I feel like I could go anywhere in our Trooper. It still looks sharp, but at 6'4" and 300 lb. it is a little cramped for me in the drivers seat. My kids have much more space in the back seat than they do in my Rodeo.
Great and reliable vehicle, it has a strong unstoppable motor, automatic trans but it works great, 4wd works well never have had a single issue. has 225,176 miles. still stronger then ever runs like brand new. Have all paperwork on it its well maintained i would never want more from it.
