There are eight of them.
You really have to enlarge the picture by clicking on it to get the full impact.

There is also the logo of the firefighters union.

There are three in the middle. The biggest has a motor cycle wearing the number “15” with the word “FUEL” in larger letters next to the rider.
“2007 EAA” with a plane flying out of the letters is to the left.
Beneath the EAA sticker is an English dragon standing up with “Sport Kilt” above the crest.
And, at the bottom is a White Sox
So, we know this car is owned by a male, fire fighting, motor cycle riding, White Sox fan and, maybe, that he wears kilts and vacations in Baja.
Can you come up with anything else?
