Query: Corvette: A Buyers Guide

Given the small size of the book the detail is excellent and accurate. The book was published in black and white (including illustrations) which limited the identification of Corvette models. For example, the corvette Anniversary model in the 1980's has body colored alloys and a different sort of pillar on the door.The book is very useful if you are wanting to purchase a corvette as it has engine numbers, colours and all details from that date so that you know all the real details of the car.Perhaps the next addition will have colored pictures, considering that most aspects of a car are viewed and it is important to identify the subtle details of a vehicle, especially special features (ie. anniversary cars).
