New cars that have been maintained, so much isn't the mileage as its age is a factor. Good example is I have a 1994 jeep with 180K on it and my uncle has a 1993 1500 Chevy pickup that has a TBI 350 and only 65K miles on it and he bought it new. Kinda like my jeep, every time you turn around something has gone bad on both vehicles as its mostly always sensors or the accessories like the alternator that has finally failed not anything major on the drive train. I have a small fleet of trucks at work. All of the trucks are 2006 and newer and we keep them to about 150-180K miles and only thing gets changed is the tires, brakes, and oil changes. Our 4.6L triton engines we don't even tune up at 100K miles as there still getting 15.5 MPG since they where new, no check engine lights, passing emission. We got rid of one about 6 months ago with 180K miles with factory spark plugs!
