I have a 96 Jeep Grand Cherokee Laredo now, 198k miles on it, with the 5.x liter engine (I can never remember that goddamn number, it's the old Dodge 318 engine, that thing is bulletproof) and I'd personally stick with that vehicle in a zombie apocalypse over just about anything else. I also once owned a 71 GTO with the 400cid engine and "4 on the floor" transmission in it. I could (and did) do everything on that car myself. Pulled the heads to get the valves ground and lapped, changed the oil, flushed the cooling system, adjusted points and timing, changed the alternator, regulator, belts, fuel pump, water pump, and the clutch (4 times, I was a leadfoot and hard on the clutch), and all of that with just home shop tools. You name it, I did it. That car only went to a shop for wheel alignments and new shocks (because I didn't have the tools).
That said, Jack stuck with what he knew, even though he knew it was old and not maintained as best it could have been. Neither he nor I would have have swapped his Charger (or my GTO) for a VW bus because I, and I think he, know nothing about VW's. It's a matter of choosing the devil you know versus the devil you don't.
And if I remember correctly, all Chargers equipped like his had analog gauges for oil pressure, engine temp, tachometer, and (I think) oil temp.
But all of us are speculating, since we aren't writing this story.
