Yep. Raced cars and bikes for years. Though my sponsorships were factory and factory support. Much different than what you are referring to.

The type of sponsorship you are referring to is not rare, but slimy. You usually get little to nothing out of it and they end up turning your car into THEIR billboard, not yours. I have quire a few friends who have stereo shop sponsorships for their cars and they attend events to showcase the audio goods and install craftsmanship. They had nice cars before. Now their cars are glowing music boxes that stepped out of a time machine from 1991. And the best they get from it is they crap in the car and small discounts on audio gear. And failure to attend "required" events is forfeiture of sponsorship.

As for the VX, again, it depends on WHAT you want to highlight. You want offroad gear, go talk to some local truck customizing shops. I know around here, it's rare for anyone to sponsor you for show, but if your vehicle has a function that can highlight the work and parts this particular shop performed on it, there is a possibility. But again, I would not expect too much. Especially with the VX (no offense). Just not mainstream enough for them to get VX business. Jeep? Hell, the world is your oyster.

Just my $.02, but again, I raced, so sponsorship was a lot different.
