I'm really tempted to get this 86 MJ with the 2.5, but I'm not sure if it would really get me much more mpg. It's selling for $800. It needs work of course, but it might be a good beater to save me some gas money driving to school and work. Not sure on the drivetrain specs, but from a picture I saw it was the 2.5. How much mpg have you MJ owners gotten? Right now I range between 13 and 15 mpg with my XJ. It literally sucks my money away, but I love the thing too much to get rid of it.
