Sean, well done for getting an online presence up - it seems the automotive industry can be quite slow in this area. Thus far it looks like you have kept things clean and simple - I cannot emphasise enough how important this is - do not clutter it. Less is more.
Just some quick notes -
In your 'checkout' or lead-capture process, it would be nice to make the process a bit clearer. E.g.
Step 1: Choose Your Product
[put tick boxes here]
What is 'ASK' ? - provide a short explanation as to what this option is.
Step 2: Enter any special requirements / or maybe 'Enter any Comments'
[text entry]
Step 3: Enter Email Address
[text entry]
Submit.
Labelling the steps makes the process easier to understand and avoids any cases where the user might be confused as to what they must do. It might be simple or obvious to you, but it could be confusing to someone else. Always err on the side of caution.
Product Info Pages
So, in an online shopping context, generally you want to give the user the most relevant information to their purchase, first. So if say I click on a product page for my car, the first thing I want to know is:
- What Products You Sell
- At What Cost
- How Do I Buy
After I see what you have on offer and how i can (immediately) buy it, if I need more information, then offer me all the background information on the manufacturer, and their credibility, and or explanation of different products (i love the diagrams fro teh suspension bushings).
Bottom line - i shouldn't have to scroll through a ton of information to see what you have and to make a purchase. I should only have to read that info if i want or need it. So my suggestion is to have all the critical info (products, pricing) and checkout/lead capture right at the top of each product page where its immediately visible, and have all the other background info further down, to avoid distracting from a potential transaction.
I Hope this helps.
