I like the simple layout; however, the images you use are too large and download slowly (mainly your head image: limo-limousine.jpeg is over 300kb!). Speed is important factor these days.
Also, on your fleet page, you use stock photos. Take a look at http://www.stretchlimochicago.com/ourfleet.htm and try to use actual photos of limos or cars.
One more thing. Once I visited your facebook page, I found weird pictures of naked man/woman. Keep your facebook page professional with photos of your limos, weddings and proms you did in your limo and stay in touch with your facebook fans with exclusive facebook deals.
Good luck in your journey to the top of chicago limo market.
