RE: High Mileage Durango
If it has been serviced and the trans has been serviced too, 118,000 is no problem.
167,000+ here and I'd jump in and drive from here (Indiana) to Florida/NewYork/California with no fears of failure.
*IF* you are still unsure, I am looking for another D for my son (his first car.) I'd be interested in buying it if you pass. PM and email me the info if you please.
