200-300K might be a bit optimistic. My Equinox will be rusted out well before that mileage. Had I not crawled under it recently to change the rear diff fluid, I never would have seen that my lower rear control arms were rusting out and needed to be replaced. 62,000 miles on the odometer.Yeah, 70k isn't much on todays vehicles. Well maintained vehicles can go 2-300k now a days.
