Looks good.
I like the look and feel of the home page, and how it talks about your love of this vehicle. It's warm and welcoming.
The about us page with the FAQ style layout feels wrong, after seeing the main page.
The products page is OK, but I feel like the images you have should be of better quality, some are grainy and distorted. Also, I would reccomend that you have smaller thumbnails oriented to the left margin of the page with the text you have above the product, to the right of the tumbnail. Then you have your more detailed page as you currently do (with better quality photos).
I will try and mock up what I mean about the producs page, and host it on my server for you to see.
EDIT: In terms of consistency, your directions page should have the light grey background as well.
Also, these are my opinions, should yours differ, then great, I am by no means the end all be all source on design.
