Back in 2003, my wife insisted that we buy a Pontiac Montana. I was against it, because I knew how unreliable Amercian cars are. Turns out I was wrong. After 9 years and 120K miles, it has been very reliable.
The only weak spot has been front lower control arm bushings - they were shot at 70K, and are starting to tear again. Not a big deal, complete LCA assemblies are cheap and easy to replace. And the left rear power window motor is dead.
Other than that, it has only needed normal maintenance (fluids, filters, etc) and wear items like light bulbs, tires, brakes, shocks/struts and serpentine belt.
