Auto Sales Website

I have a website template already for this project.? I need the template edited to fit my purposes.? I also need a "Make" "Model" and "Year" drop down menus/data base. A similar data base can be seen at autotrader.com...if you are unsure. However the Make, Model and Year fields are all I require. I will require e-commerce integration and the ability to allow members to subscribe to my website. Pages:? Home, About Us, Contact, Request Vehicle, Shipping, FAQ,? Terms & Conditions, Privacy Policy? and Buy It Now.
