I must go to bat for Kent. While some of his products and information may seem to be overpriced, his videos, pamphlets and well thought-out kits are a boon to those who are venturing into DIY maintenance of our old benz cars.

Those of us who are more advanced amateur wrenches can denigrate his products but they can be invaluable to the newbies. To offer a specific, I could not have repaired my W123 sunroof without his pamphlet and maintenance kit.
