Stay in the Bay: Wolfgang Koehler and Andy Campbell's Road to a Leaner and More Profitable After-sales Department Paperback – July 17, 2020

Excellent book for auto service professionals working in dealers or independent auto workshops. Wolfgang is no-nonsense, and calls a spade a spade, which is the best way to share information because honest people are authentic. I highly recommend it.

I purchased the book, read it and loved it. I've already applied some principles in my BMW Service Department and look forward to more. Thank you Wolfgang and Andy.
