This is a great vehicle. As long as you take care of the basic maintenance it will run forever. The offroad performance is also very good. Highway is comfortable. I have the I6 4.0 engine. Power sunroof and leather seats. Black inside and out. The only thing that is a knock on the vehicle is the highway. There is some hesitation when going from overdrive to one of the lower gears. That is to be expected with the I6. But overall it isn't a big deal because if you lower the throttle even more the it can really move. The gas mileage is as follows. 60-67 23-24 mpg. 67-74 21-18 mpg. City speeds it is about 15-16 mpg. Great vehicle for Michigan, not to mention it was and still is made in Detroit.
Selec-Trac 4x4 is great. Sunroof is too.
