Nobody who isn't fairly ignorant would've been surprised if it was a 4cyl 5spd Ford Ranger, an old Volvo 240, an 2000s diesel dodge or GM, a crown vic cop car, a Honda Accord, a Ford E-series or Chevy Savannah etc, etc. Somewhere there's probably a rusted out '99ish Grand Caravan that's close to a mil and on it's 6th transmission.

Pretty much every vehicle that isn't equipped with some achilles heel or highly engineered to a price point can go a mil if you take reasonably good care of it and don't mind throwing 0-1 engines and 2-4 transmissions in.

tbh I was guessing Volvo 240-series. I suspect cockroaches will be driving those battleships around after the bomb/climate collapse/asteroid/big crunch.
