This You Tuber Bill is a car salesman. He puts out the best car review/sales pitch videos that I have ever seen. He is a down-to-earth real guy and appears to be pretty honest and unfiltered. He recently did a video on the W220. I urge you to check this video out as well as the rest of his library.
Enjoy!

I watch Bill all the time. He's one hilarious Boomer I nearly lose it when he complains about birds and creatures attacking him when he tries to film, lol.
