My parents just bought me a car and it was pretty cheap only 1800 or so and it is a stick shift mazda 626. Its from year 1997 and has 152k miles on it. When my parents got it checked out at the mechanics before we bought it, they said everything looked fine. Everything feels fine when i drive it except for a slight shaking when i'm stopped. I'm just worried that it will die soon because it already has 152k miles on it. What are your thoughts?
