Guys, I am coming from Toyota world. I am bored of Tacoma and really like the way Rubicon unlimited looks and performs. However, I always heard that Jeep quality not so good, but I understand that lots of American cars/tracks improved its quality over the years. So basically if I get a a used unlimited Rubi with under 30K miles, what troubles should I expect from it if I keep it until 150K miles? I am looking to get one with the auto tranny.
