If that 3,500lb car has to get pulled up just a few inches, the amount of force required get multiplied by a large factor.

I can push my empty 3,500lb car on a flat surface all day long, but the car stopped, with a 4" ledge in front of it? No way, not ever.

The only way I'd attempt this was if it were a life/death situation, otherwise your car is better used to drive to find somebody with a 4x4.
