I bought my Jeep in 2006 with 26 miles on it and basically have driven it crazy to the tune of 103,000 miles with no engine problems at all. Only negative I'd have to say is the Goodyear tires that came with the vehicle were awful, I replaced them with Fusion XTI and its been great since...keep up the scheduled maint. and it will keep running.
