Saw this on my way home from lunch, couldn't believe my eyes so I had to turn around and get a picture. I actually didn't read what looked like For Sale on the window until I just sent it to my computer from my phone.
Yes that is a skateboard as a wing, YES that is two fountain cups and YES that is string holding it to the car.
Nice, the authentic wood grain gives it a nice upscale look!
As for the other one that is definately a joke...Hell when my old pos lost a hubcap i duct taped a frisbee to the wheel and drove around for a few days just for fun.
