You nerd to check that it has been maintained. There should be paperwork to prove this. If it has been correctly maintained, should be no problem

146,555 miles. Seriously, nobody can say how long any car is going to last regardless of make/model, age, or mileage. It depends on its current condition, how it'll be driven, and how well it'll be maintained. It MIGHT make it to 200K and beyond, but maybe not. It might crap out tomorrow. Who knows.
