2000 Subaru Outback Damage from impact-crashed into to

My 2000 Subaru Outback Wagon was crashed into yesterday by someone who fell asleep at the wheel. No one was in our car-it was parked. It was hit head on and I am guessing speed was between 25-35mph-it was a Ford Ranger pickup truck, both his airbags deployed. My concern is the damage to the auto transmission, the differential and other components since the car was physically moved about a car space and a half with the impact. The front end being pushed into the radiator, fan, flywheels. Anything specifically I should be asking for questions of my mechanics? I'm reluctant to have it towed to just a body shop b/c of things that could be overlooked. Is it likely that speed impact would impact the frame/front end and possibly a loss? Trying to ensure I am firing off the right questions. Thanks
