One of my best friends got into an accident on his cavalier about 2 years ago. He messed up the front end pretty godd but the engine and transmission still worked right afterwards to where he could drive it still. The problem is he didn't have insurance on the car at the time so the car has been sitting for about 2 years. Right now we know the battery is dead, rad is busted, front quarter panels and bumper messed up bad, broken windshield, and the frame is tweaked on the drivers side. The car is in mint condition otherwise.

What would it take to get this car going again? I know for about $700 we can get a cav body kit that will replace most of the damaged body panels but how about starting that engine back up after so long? Can we just clean it up a little and crank in over or will there need to be more done before that can happen? This car has really low miles on it (it wasn't very old at all when this happened) and still smells like a new car inside. We have any hope on this one?

Yep, but for serioius frame damage you'll want to have a shop do it/get a donated front end.... Hell if yoiu're doing it... throw in a 3800.....

Drain the oil. Remove the spark plugs and valve covers. With the pan still under the car, douse the valvetrain with a light oil (5w30), and let it soak for about an hour. Squirt some oil into each cylinder through the spark plug holes. Let this sit for an hour also. Now fill the car with oil.

Hand crank the engine using a breaker bar and the right sized sprocket from the crank pulley. Several times. If things seem pretty free, re-install the old plugs (so you don't foul new ones), and try to light it off. If you get it going, change the oil after it'* run for about an hour. Then change the plugs.
