Advice about what gear to take photos/videos of dealership inventory

I have been asked to help out single location dealership in Ireland with ideas for their social media.

My question is how are dealerships photographing/ or filming their inventory? Do you have a dedicated kit that everyone has access to so that the quality of video or photos remain the same?

Would you suggest smart phone, or something like a DJI Osmo pocket three for videos and a good camera for stills?
