The cherokee and GC are still both pretty reliable, as cars go. You won't likely have any major failure. I've heard that the 4.0L eats O2 sensors and Rear main seals though. But it is one of those cars that will start everytime, all the time.

I have owned 3 of them same problem , a few times.
you will not like a jeep. 12 mpg on a good day.run run run away.
the grand cherokee had a good engine and nothing else. look at consumer reports. get a previa or sienna if you want more space.
Sienna, yuck. Ugly and toyota's worst in quality. (I also looked at one of these, for the heck of it. No. No no no. And as far as gas mileage is concerned, the GC is capable of 17, 18mpg or better on the highway, depending on how you drive. I've seen people say they've gotten at least 20mpg on the interstate.
