if its the I6 engine that thing is bulletproof. i have a 93 grand cherokee with the I6 and it has 210,000 miles on it and it runs like a champ. i also have an 01 wrangler, also with the I6, that has 136,000 miles on it and it runs like new. those I6 engines easily, with proper maintenance, could get 300,000 miles. My 93 grand cherokee has driven from wisconsin to texas with 180,000 miles on it and it did fine. and i regularly drive my wrangler from corpus to dallas (8 hours) and it does fine.
