Being in NH I can tell you the photos I saw of a row of SAABs at the local dealer in Exeter was shocking! It looked like the hoods had been beaten with hammers the dents were so deep. I never could imagine hail could do that much damage...I figured just some light pock marks but these were real deep divets! The dealer claimed that all of the cars on the lot would be totalled!

Talk about being in the wrong place at the wrong time! OUCH!
If the damage to your car is limited to the hood, trunk lid and roof you can probably get the hood and trunk lid from a junk yard and get the roof repaired and the car painted and be good to go again. I would guess you'd be spending about $2000 but on the bright side it is cheaper than a new car.
