I agree that this video is poor from a production point of view but personally I dont care about that, I find it useful seeing vehicles side by side whether he reads from a script or not. Remember some guys make a living make YouTube videos and some are well produced and edited.
As for the sales exec not knowing his/her product, just remember they are dealing with a complete spectrum of models / colors /specs / options - even the best sales guys dont know everything although some are MUCH better than others
