This is an exceptionnal tool, should you plan to buy a car.
The data about the reliability and the frequency of repair of most of the cars available on the market is compiled from information supplied by car users like you and me.
Sections about fuel consumption, tire performance, etc. are very informative. I relied on the comments in the book to purchase new tires and they were extremely accurate.
We have 3 cars at home (1998-2001-2003) and the book's comments are right on the button.
This book will shorten the shopping aspect of the car you consider buying by a lot. aAnd if you just bought one, look at the data in the book to forecast where the problems on you car will start with.
