Why not combine both worlds and get some "free" visibility on the street. 

Here's the deal:  I get my '09 Jetta wrapped to look like a big PBR can.  It is Laser Blue, which coincidentally matches the blue on the PBR can perfectly. (Yes, I have compared.)  I set up a booth at the big East Coast shows and sell or give away PBR stickers, t-shirts...you know, the typical PR stuff.

In return PBR sponsors a bit of modification to get the car a little more notice and draw attention.  I would take and post pictures on your site.

Sounds like a win-win to me.
