I bought a cj7. It should be ready for the apocalypse, amc360, np435, re4.5, Mallory hei, completely rewired, custom dash, corbeau seats, bfg km2 35's, g2 one piece axles...and of course...headers and glass packs. + a lot of other odds and ends.
both are nice, I personally think the 2nd would do better in a hoard situation. better rate of fire, but what about your jeeps? any armor, heavy duty bumpers, extended fuel tanks, roll bar machine gun mounts? that kinda thing.
