Snorkels - Good thing, bad thing?

[Alexlebrit]

I've been reading about snorkels and am still not certain if they're a good thing or a bad thing for overlanding. As about half the route's on the road and the other half will only have the occasional river crossing, perhaps I don't need one, but then again it's better to have and not need than to need and not have.

And of course the next tricky bit is that there's no snorkel for a Fiat Panda, so of course I'd have to make/mod one. Anyone done this and have any tips for what to and what not to do?

You've got to admit though, it's doesn't look half bad.
