Overall Jthemes provide great support. I recommend his product. keep updating this script, it's great.

Here the suggested feature to add soon as possible: CVS Import in Admin area, Review system where user can review a car, Add Instagram instead of Flickr, Add a listing feature to allow user to submit their listing.

Allow user to be able to submit listing through CSV file for lisiting car catalogue. This option will be good for Car Dealership user. Here a great business view: Listen your customer and solving their issue is the key to success. Best!
