Nice start! I do like the graphics.
Some hints above and beyond what others have noted (do with as you please

):
Consider using a smaller version of your website graphic on the subordinate pages.
Try putting a b it of vertical space between the Before and After sections so they are more easily recognizable.
Consider a smaller manufacturer logo as well and put it on the same line as the year and model info (less wasted vertical space).
Too make it more classy (although it creates more work) think about making the manufacturer, model and year info a graphic as well (instead of plain text).
Try sharpening up some of the pics as they look too out-of-focus.
Try framing some of the photos (either directly in the photos or with a TABLE tag) to give them a bit more professional presentation (which goes along with your professional-looking site graphics). Here's a link to one of my photos:
2004 Acura TSX
Change your footer line so that only the e-mail address is the actual link instead of the entire line itself (will help it to stand out more).
Think about a subtle background image for the pages (gives them a professional touch that stands apart from just plain white).
In closing, you're off to a great start! Keep it rolling and best of luck with it!
