The book has a very good collection of articles from many important car magazines like Motor Trend, Car and Driver, Motor Sport, Road & track, etc. they all are articles talking about Porsches from 1990 to 1997 and cover comparison tests, specifications, performance and model specific details. If you like to buy and keep these type of magazines for certain articles, AND, you are a 911 fan, this is the book for you! I'd like a porsche company edition myself but this is a very nice collection from other magazines articles.
