Let me explain the idea. The demo site presents the site of the company that sells used cars (new ones are also acceptable :) ). The company consists of 3 selling agencies (dealers) located in 3 different cities (you can create 1 or more sellers). The site gives the possibility to create an account for an employee of dealer agency to let them enter car offers that come to the company. This way all offers from each agency are placed in the same database and clients can see all of them or filter cars by the separate agency.

What is more, there is an option Add To Quote that you may find very useful.

The company offers also other services like road assistance, car rental, repair, and care or financial services. Let's assume that the client wants to buy one of the cars (or more) that need repairing then asking about the quote the dealer may calculate all costs, give discount etc. Also, take a look at all available gallery views navigating Extensions -> DJ-MediaTools. The gallery extension is compatible with DJ-Catalog2 it means that you can display items seamlessly in the gallery.
