Query: Excellent Books

...It's VERY worthwhile buying seeing that it tells you EVERYTHING about your car, and how to repair them inc. sensors, brakes, lights, replacing transmission gears, head gaskets ect...It's the only book you need. I have one for my Sunbird, Topaz GS, Topaz L and my 2001 Malibu LS
