The quality is the main difference. And 200k is pretty rare anymore, we see more problems on newer vehicles then ones manuf. before 08 at the dealership I work at( chevy, buick, gmc, toyota, scion). Everybody is pinching that penny and quality is suffering. It also doesn't help that everything has been recycled so many times that the molecular structure has changed to were metal is not the same.
That is my experiance and opinion for what its worth!
