sometimes VWOA (Volkswagen of America) gets ruffled a bit. They don't really mind the old Beetle shape being used in our field as much as the New beetle shape. They probably felt his stylized version was too close to the New.
I got licensed through VWOA about 5 years ago. I have never had a problem with them on anything I've done. I've met with them when they were here in Tucson and I have done work for our local VW dealership (Chapman) so it's been pleasent.
I would reccommend you go to your local dealership and let them know who you are and what you do. They have needs like any other company and opportunities to get paid and solidify your position in the market exist there.
