It contains a driveable Unreal vehicle along with blueprint and is properly rigged and ready to play. The blend file is also provided and has all the textures packed so you don't need to download it separately. In the unreal project also everything is set up. You just need to migrate it to your game or scene. Currectly it is very high poly so please don't use it in any mobile based games for example. You can use inbuilt triangle reduction in unreal to create LODs and you may need them if you are using a lot of the vehicles of this particular model in your world.
