FWIW, I doubt your dealer will be getting a BV 350 since in order to get the new scoot in the US a dealer has to have at least one mechanic certified to work on it. My dealer in Houston sent I theirs a couple months ago. They have a BV 350 that I had a chance to sit on a couple weeks ago.
Over on Modern Vespa we've heard some bitching from dealers who were not happy with the new policy of requiring factory trained mechanics but frankly I was pleased to hear it.
I'm considering trading in one of our BV 500s for the new 350.
