Exactly what All4 says.
Honestly, after this conversation I'm somewhat tempted to make a Gremlins character who insists on using old-fashioned stuff whenever and wherever possible. Either it won't have moving parts (armor, melee weapons), or it'll be pre-1950 tech (guns). The rest, like cars, he'll just have to suffer through. That's because IN CHARACTER, he'd have to be a stone blind IDIOT not to realise that newer, higher-tech stuff just BREAKS around him, or otherwise acts screwy and fails to do what it's supposed to - so he's come to appreciate "the good old days" of durable, low-complexity engineering. Revolvers, for example.
