I have the 2003 edition, and it was my first Catalogue Raisonné. And, to be honest, I found it a little bit disappointing... I expected it to be the absolute bible about Maserati, and in my opinion, it could be better...
For example, there is no "family picture" of all the Maserati brothers, or even some informations of their heirs... No pictures too of that "famous" Neptune statue in Bologna which gave inspiration to Mario Maserati for the brand Trident.
The text is very "politically correct", too : not much about the shortcomings of the De Tomaso-era ! In fact, there is more pictures for the launch of the Biturbo than for the original Ghibli or the Khamsin !
I was hoping more pictures of the assembly line at different periods, technical drawings or even photos of Maserati stands at Motorshows.
No more production figures after the Indy, why ?
The text doesn't tell much about the technical study of each car.
And this book doesn't show at all the "side projects" (not a single picture of a SM or even the (awful !) Chrysler TC by Maserati) or the Maserati-engined show-cars (for example, Medici I and II by Giugiaro...).
It still a "must have", but it could have been much better. In my humble opinion, you'll still need another book, like the one by Maurizio Tabbuchi.
