Book excerpt: For over 25 years Rob Siegel has written a monthly column called "The Hack Mechanic" for the BMW Car Club of America's magazine Roundel. In Memoirs of a Hack Mechanic, Rob Siegel shares his secrets to buying, fixing, and driving cool cars without risking the kids' tuition money or destroying his marriage. And that's something to brag about considering the dozens of cars, including twenty-five BMW 2002s, that have passed through his garage over the past three decades. With a steady dose of irreverent humor, Memoirs of a Hack Mechanic blends car stories, DIY advice, and cautionary tales in a way that will resonate with the car-obsessed (and the people who love them).
