I have a magnesium firestarter. I choose Option 1.
I figure that a beat up truck that has lasted this long will last a bit longer. Not as flashy as a new car, but more ready to go off-road (if it still works). Even if it doesn't work, there may be some outdoor equipment stashed in the glovebox or in the cab.
I didn't choose Option 2 because a sports car will only be helpful on main roads. In the condition the city is in now, that won't be helpful for much longer.
I didn't choose Option 3 because time is of the essence and with night coming quickly it is only worth checking one vehicle.
I didn't choose Option 4 because the chance of getting a working vehicle is worth the risk.
