I agree that for the most part he repeats himself and rehashes topics a LOT, mostly to sell you some finagled tool to justify the "fix", but I must admit that he has a wealth of hard earned knowledge and especially when I started wrenching on Benzes I learnt a ton from his videos. Especially the earlier longer videos are gold. One that jumps to mind is the W116 tail light gasket replacement, excellent and thorough.
