Just a few points about you site from a layman, as requested.

I like your company you seem to do everything needed to do with cars and car recovery. What I feel needed is that a few tweaks to you site that would enhance it and improve the overall feel in my opinion.
I would like to see a better heading instead of just large pink lettering. Even pink lettering drop shadowed or bevelled/embossed would improve it, maybe a pink truck logo or clip-art would not go amiss. I would also like to see this style used at the head of every page.
I feel your thumbnail pictures are too wide and do not fit into your background properly making me have to scroll to the right needlessly. Also there is no return arrow from the larger picture back from clicking on the thumbnail.
I don`t really like you button choices. The change to green on mouseover is to slow and does not fit into you colour scheme. I think it would work better with smaller more dynamic buttons.
Your text would look better centred as you have it on you Contact Us page. Your text should all be the same colour, size and font on some pages it`s bold or blue or black or whatever.
I also think you should use bullet lists especially on you Roadside Assistance page, instead of highlighted blue words. I kept clicking on these thinking they were links.

Just a few gripes..
