Be sure to document the disinterment, old car magazines love his kind of stuff.

As other have said, be careful in moving it, the brakes are likely locked up, the engine may or may not turn. I'd be very careful jacking it up, if it is very rusty the jack can go through the frame / body and land on you. To move it I'd be real tempted to source a paid of tow truck "repo" dolly wheels.. These are 2 small wheels per side and come cross bars, most are self jacking. Think of a axle / mini trailer that goes left to right directly under a pair of car wheels. This way you can roll the car out and get to hard pavement to better asses the situation, get the wheels rolling.

Resist the urge to try and get the motor running without a very specific amount of work, you may end up causing more damage. ( A motor stuck due to leaded fuel / light rust can be made to turn and run but otherwise usable pistons will be damaged and maybe score the bore beyond repair. )
