I bought my Mountaineer used in 2003. It has now reached 222000 miles and I just had it inspected. Needed a few spark plugs but that was it. I asked if the engine and transmission were ok and the mechanic said they were. I love this car. I am looking for another used suv, not because anything is wrong with the mountaineer, I'm just getting worried about mileage. But, I won't be selling it. It will take my daughter to school when she starts driving. They are hard to find used because everyone hangs on to them. This is the best vehicle I ever owned.
nothing, the v8 engine eats gas but if you want a powerful suv it is the trade off you have to be willing to make.
