auto trader

I need a web site similar to autotrader.co.uk. It requires to design a website and some programming at the back end. As [login to view URL] is multifunctional web site I don't require all functions from that site. I need from aututrader is "searching cars" function but slightly different( where you choose a location and makes of cars) and Advanced search part. Also, user must be able to submit vehicle dimensions he/she is interested in, and when there is such a car found he/she gets informed by email. And, Selling vehicle part. (user details, car details, images to upload), user must be able to login and change required details if required. Get price function: user must be able quote Other pages will be advertisement pages of: displaying insurance companies contact details, news, new regulations and law, services: car wash, driving schools, ect.....
