Is that possible i create a car portal with Car review Car DB (previous car model, prices) Car store Car Classifields all in one installation ? possible ? is it hard to setup a site like this ???
By using joomla you do anything you want, just find the jommla component or extension then install it. the installation is very simple. For example: th car store ca be made by installing VirtueMart, the program is free (open source), and the installation is very simple.
In one installation I don't think it is possible. You will need to pick up and install a few extensions that give you the functionality you want. There are lots of free extensions that will do what you want, but I think you might end up having to pay for one or two that really get what you want done.
