I've owned two Hondas. Both were blowing blue somke well before 115,000. The first one had the rear suspension collapse befor it was relegated to the junk yard. Yes, the oil was changed regularly at 3000 mile intervals.
I have owned a Ford Bronco II (always blew its transmission gasket at any speed above 70), 1990 Chavy Suburban ( it was great until about 135000 miles, then began to fall apart), 1982 VW Rabbit convertible (Still would be running great, except I lost interest at about 100000). 1984 Jetta GLI (It was a runner and perhaps the closest thing to my R/t, but I sold it at 125000 with no problems), Nissan Sentra (New family and it did'n't have air so we traded it for the Jetta), 1994 4Runner (which I still own and it has been awsome, except for the recall on the head gaskets and the failing starter)
Point is, no car is perfect, and I've owned many of them. I am also familiar with my father cars. In High school I drove a 74 Buick Wagon, 76 BMW 530i, 81 BMW 528i, etc; and non of those cars were wihout their problems.
I now am the proud owner of a 00 Intrepid R/T. Purchased it new the day after X-max in 00 and have no problems. It has almost 16000 miles now and the only service it has had is oil changes. No complaints, no problems.
Don't exactly know what you're problems are Tom, but at 70000, it seems that "small" problems are hardly worth complaining about on an enthusiast site. Seems that the car has treated you reasonably well for that milage. Call me crazy, but give it a thought anyway.
