I found an 05 Jeep Grand Cherokee for $9000 with 111k miles. It's a V6 with 4WD. According to NADA, this is a pretty good deal, but what is the reliability like? I know that Jeeps are bad with gas mileage but I can deal with that. I just want something that is reliable and relatively safe, as well as something with 4WD as I live in an area with long winters with lots of ice and snow. Any advice would be helpful!
