The Mitsubishi "Pajero" is called "Montero" in Spanish speaking countries. Again in Spanish, "Pajero" means "wanker".
Naah, that is a myth that has been debunked some 20 years ago:

It is curious how it still surfaces from time to time.

If you mean “in Spanish-speaking countries”, alright. In Portuguese “nova” just means “new”, just as French's “nouveau” or Italian's “nuova”.
I'm skeptical of that. "go" isn't really idiomatic for "work" in English, and in Romance languages, you're going to use the local variant of "marcher" (literally "to walk") or "to function" to refer to technology working, so I suspect using the literal translation of "to go" is going to be a very strained idiomatic relationship at best.
