Thanks for the input and replies. My target market is 16-30 female and males. It will greatly depend on the design, obviously not many males will buy hibiscus flowers. I plan on unveiling a new design each month. As far as a patent is concerned, no I don`t think it can be patented as it is an existing product just a different application. Did some research and was fairly sure not patentable. I did file a trademark for the name Art Z Cars.
This logo won`t actually be on a vehicle, only the decorative decals will. This is for the product header, biz cards, website, and promo material. About the website, it is a very very rough draft. I needed to get samples of my products online for a business meeting and that was about the extent of my abilities.
Thanks for the input, it help enormously.
Booklover,
My business is going to have 3 different branches.
1. Novelty/gift
2. Business advertising/Political
3. School mascot/logos
It really is a exceptional product, especially when compared to magnets or permanent decals.

Grill Charmer,
I happen to drive a blue minivan and have purple hibiscus flower all over it. I get a ribbing or two but you`d be surprised how many cars stop me, and not all youngsters, wanting the decals. Don`t have to adorn the whole car, you can just do the back, side, hood, whatever you want. That`s the whole concept, put 1 on or put them all on. Also doing holiday themes and wedding, birthday etc. My brain no longer stops at bed time.. What a change from my flight attendant days... Exhilarating.....
