What fuel is going to be available in this doomsday scenario and how much of it will you have? My answer to the OP is probably an old Land Cruiser or Jeep, YJ or older. I'm just curious how useful a vehicle is in a doomsday scenario. Guess it depends on your definition of doomsday.
Exactly what I always say whenever this thought experiment comes up. All gas would quickly get used up within weeks if not days from widespread panic and hoarding, and any gas you happen to hoard for yourself would all go bad within 6 months to a year. Also good luck on obtaining any motor oil for your required oil change after a few months.
Wall-E had it completely right. The only machinery that will actually be worth a damn are ones that run purely on electrical power (ie. EVs), not dead dinosaurs. So something like the Hummer EV or a converted Hummer H1 would be an ideal doomsday vehicle.
See even then we have different definitions of doomsday. Unless you have solar panels on your home electricity isn't going to be there for very long. To me doomsday means a general breakdown of civilization and that's going to come with a cessation of public services. I can't see a scenario that we call doomsday where we have electricity in our homes. That feels like the glamping version of doomsday where it's not really all that rough.
A fearful society is a compliant society. That's why Democrats and criminals prefer their victims to be unarmed. Gun Control is not about guns, it's about control.
My doomsday vehicle will have pedals and 29" tires.
Gasoline stock will run out in weeks.
If there is electrical issues pumps won't run.
And manually pumping from a station's stock tanks is a vapor cloud explosion nightmare. And tactically unsound to put yourself in a position to be robbed by a large group.
Yes doomsday does also mean no electricity from regular government entities anymore for me. That's why you'll need solar as you mentioned and also why I said the movie Wall-E had it correct since he uses solar to charge himself up in his doomsday world. You as a regular individual person needs to sustain yourself and that is much much more doable today to produce your own electricity through solar or any other means (hydro, wind, human, gravity, etc.) than trying to produce your own gasoline.

Stick a battery and electric motor that has regen capabilities on there and you'll have the perfect vehicle to get around no matter your resource situation. Use the battery power whenever you do have it from regenerative braking and other charging means, and use leg power whenever you run out of battery.
