This place is such a scam. After researching their phone numbers, I found that they have many other phone numbers and websites:

(773) 992-0902   (312) 364-1300   (847) 605-4100

Websites:
airportchicagolimo.com
chicagolandweddinglimo.com
allamericanlimobus.com
allamericanlimo.com

Wonder why a business would have so many websites/names and phone numbers? Hm, its because the business is basically family-run, and they are not only a) late b) unprofessional c) unprofessional appearance-wise (it was an embarrassment when we were picked up...i thought it was a joke) d) they add charges that you did not authorize and finally, e) they present themselves as a 'wedding limo company' - don't ruin my day just because you want to make a buck or two

This company should be dissolved. After reading reviews on other sites, I should have known better. Unfortunately, it was the only bad part of what you could call a perfect day.
