I'm looking for car-shaped balloons - normal size (10-20 inches, give
or take).  They would ideally be made of mylar (the metalic stuff) but
could be rubber.  They would be helium inflatable so they float in the
air.  I'm looking for more generic stuff (i.e. I've seen balloons in
the shape of race cars, or fire trucks.  Those are good, and please
list any you find, but I'm more looking for generic looking cars.)

Bonus:  If you also find a bucket-shaped balloon.  Or Sponge shaped. 
Or anything that might symbolize a hand car wash, I will pay $20,
total (for both links to car shaped baloons and bucket/sponge/etc.
shapes.) and will give the extra 10 in a tip.

Here is a cute car-shaped balloon:
