only thing i was left wanting to see was better shots of the fleets. i'd get a gallery up with multiple views of the different cars in the fleet. otherwise a really good site for the purpose. grats!
try and get higher on google for more business and make sure you put your number all over your website.
The site has a very attractive feel about it - class to go with classy transport. Good job! The only thing I would just suggest is that you have someone go over the spelling and grammar for you as there are a few errors that might detract from the professionalism that you wish to portray. As an experienced editor, I know how difficult it is to see your own mistakes, so if you have a friend who has a good grasp of proper English and a detailed eye, drag them to your site in exchange for a limo ride some evening.
