I'm thinking of buying a Jeep Wrangler used and paying cash, so $5000 or less. I'll be using it on the weekends for offroading and that's it. I was thinking of buying one of the models with a 4cyl and then just put 31in muds on it and leave it at that. The trails I want to run are mostly just mud and stock friendly. How dependable are the 4cyls? I see them with like 129k on them, but are they reliable at that point? Would you all recommend the 4.0L over the 2.5L?
