@Fushiginiku well. not really, it means that, but in the case of NOVA, I remember that there was an issue with fuel brands, NOVA was a brand of fuel with lead and the car had that name aswell, it is like "The Thing" of Volkswagen, in Mexico it was called "Safari", but in US there was a car with thar name if I remember correctly.
However, "no va" is a clever way to say that it does not run, now that you mention it XD.
