Much of the text on the site is gray on a black background which does not offer the contrast to be easily read. I can not find a listing of the fleet vehicles available, or the rates for limo services anywhere on the site. These are probably two of the most wanted pieces of information people are going to be looking for on the site. There are several grammatical and punctuation errors that should be corrected.

The sidebar looks like a list of clickable links but does not have any links, The header is not consistent from page to page. When viewed on a wide screen monitor there is a bunch of "whitespace" as well as the text is stretched so wide that it is uncomfortable to read.

Even though some limos are black, the website looks kind of dark and doesn't give a friendly vibe to it. However, I have to admit that it is clean and organized. I'd add a 4th picture to the three other limo pictures you have already and maybe change the gray box on the bottom left.
