Never get under a car that is not blocked and on jack stands.
A car rolled onto my dad while moving the shifter under the car. It trapped and killed him before he was found by my mom. I pulled him out and tried desperately to save him doing CPR until the rescue squad arrived.
This car killed 3 people, 2 before I bought it. Mamed one after and burned an apt down. Yes the real "Christine" . A story I hate reliving. The car had less then 200 miles on it. I bought it at an old salvage yard.
