The component is well thought off, but should be a little more intuitive and provide the user with some more possibilities. Although you can do the changes yourself, sometimes you don't really need to change the code, and like the example in demo, just using J! and some available options you can make things happen.
However, we think it's in the good way and with some more improvement will be one of the top.SEF option, more detail search, and some adjustments in the layout, and in our case is more then enough. Frontend is possible, although is more focus to work with backoffice.
Overall we do recommend this component if you plan to start a simple site to show your cars, or for your clients, since it as a simple backoffice not very complicated to work with.
