The car, as it stands and by itself, is an excellent shelter against the cold, wind and wetness. The fully functional engine could even provide some heat for a limited time - until the gas runs out.

The really challenging part would be improvising a heat source inside the vehicle. Given more tools and a lot of time and dedication, perhaps the exhaust muffler and piping could be made into a wood stove?


As for the scavening part - it really depends on the situation.
