The reason for this books low rating is its title. Someone wanting to learn how to draw cars really should look elsewhere. While there is a section on perspective, drawing and rendering techniques, it is very brief and feels like something of an afterthought.
What you get instead is an in-depth look at the car design industry, and input from some of the very best designers working today. Much of it is subjective, with various people submitting their favourite current cars, and a list of the ten 'most influential concept cars of all time', but you get the sense that the contributors really do know what they are talking about. Interiors and concept cars get their own sections, and there is also a useful timeline of design trends, masquerading as a list of landmark designs.
Aside from a few photographs crossing the centre-line, the book is beautifully presented. The very readable text is quite informative, and some brilliant sketches and renderings sit alongside the many photographs.
This book will not appeal to everyone and will frustrate those who expect a drawing guide, but for the people to whom I suspect it is aimed, those considering a career in transport design, there is only one word for it: perfect.
