The AT-TE from star wars in my opinion would be pretty nice to have in fallout.

For me, an M4 Sherman tank that has a flamethrower.

1967 ford mustang fastback with machine guns!

1970 Plymouth Roadrunner, with overhead blower

It'd be awesome to see some kind of dirtbike and some Humvees that have different styles for each big faction in the game

i dunno ive never really thought about it until now. id like to see a sherman or some strange conglomerate of scrap metal that for some reason has an engine hooked up to it. either those, or some sort of walker. that'd be awesome.

I'd really dig an MRAP, something with armor, mobility, and a usable gun on top. Imagine fighting off raiders by the dozen with a mounted machine gun as they charge you with lead pipes and knives. I can't find the link, but if you guys ever saw the EOD series (I know EOD uses JERRVs, but no one in Fallout uses IEDs, so no need for that kind of armoring) on whichever channel two years back, episode 6 or 7 had them surrounded by insurgents on the hills of the valley they're trying to clear and they mounted a camera on the gunner's helmet, it'd be really cool to be able to roll into the the Great Khans' canyon and have a firefight similar to that.

I'd also enjoy a vertibird, I know XRE has one, but one that doesn't kill you half the time you land. Something that you could set to hover to use a mounted minigun, think the Enclave Remnants in the battle of the dam, but whenever you want to take out large numbers of enemies with minimal risk.

I'd love a Mercedes Benz G class 6x6 mad max style. External armor plating, off road bumper with spikes, dual mounted m134's, etc...
