grand cherokee owners any info good or bad?

i looked at a JEEP GRAND CHEROKEE today. its nice. Its time to get the LADY a vehicle.
2002 J.G.C. laredo edition, 4.0l engine auto trans 2wd leather interior. 112k mi looks to be in excellent condition. I didnt have time to really look at it or drive it. They were closing and i was in a hurry, but i will go back monday morning. and do all that. Just thought i would ask here about any experience with them, good or bad. I think i have heard about electrical issues? or maybee computer? but also remeber reading good stuff on here about them.
thanx in advance for any help
