Leaving the layout look / feel / colors as they are currently provide:
1) Using the same database structure, convert the all 65 maker search files (number yet to be reported) and functions into php queries rather than asp.
2) Search function should function exactly the same way as current.
3) Remove all frames with this site and convert to HTML5 / into php loaded data. (*mobile / tablet devices are not required for initial project)
4) Previous searches must continue to be displayed as they currently are in left sidebar, displayed DURING results + car single WITHOUT a frame. This can be done in a hidden field to carry the search choices to the results page or using ajax. Which ever is easier.
5) Inquiry forms to be converted into php (from bottom of single car results search) will submit details to admin along with the template for admin reply. Also a confirmation message is sent to the visitor whom completed the form.
