I need a website very similar to autotrader.com. I have a linux server. I want clients to be able to log into a control panel to manage their vehicles, description of vehicles (features, price, etc.), personal information(email, phone number, address, business name, etc.). site should have a browse function, search function, advanced search function, etc. I need a payment system so clients can pay when signing up. I also need an admin control panel where i can manage the site. like i said before, i need a site very similar to autotrader.com.
