None of these got anywhere near 100,000 miles without requiring expensive non-routine repairs and/or being in the shop repeatedly for some recurring problem.
I bought a Toyota Corolla wagon with 30,000 miles on it. I put 110,000 more on it. It never required anything but routine maintenance.
Three years ago this month I bought a 2006 Toyota Camry with 14,000 miles on it. I'm pushing 95,000 miles now. It's needed nothing but tires, windshield wipers, a tail-light bulb, gas and oil.
I've bought my last American car.
Mercury Sable wagon
I spotted two of your problems right there. The Sable was an expensive Taurus, which, while it was a good design, had tremendous quality issues. I owned a couple (never again). All the rest of Ford's line up (at least currently) consists of very well made, reliable cars (not technology leaders, but reliable).
I have long contended that after the debacle of the 70's that all the American auto makers participated in, Ford finally got it right, with everything EXCEPT their best selling car. The Taurus was the rotten apple in the barrel that spoiled it for all the others. If it hadn't been for the quality problems the Taurus had, Ford would have a great reputation for quality. They did it to themselves, with that one lousy car.
