Why Your Car’s MPG Sticker Lies (and What You Can Actually Expect) | Car Confidential Ep.3


“... I live in a big city with lots of automobile experts, but when I want one to guest on my television program, I only want to talk to Shahe. Even more personally, when I need information about our family cars, I only want to talk to Shahe. Buying or selling a car, repairing a car, trading in a car…first I talk to Shahe. Actually, I don’t have to talk to Shahe quite as often because all I have to do now is read this book… you too, your wife and most especially your kids.”
