Hi SMYUEN,
Done with "Lexus: The Relentless Pursuit" and here's my take on it ...
The book chronicles the brief history of Lexus and its beginnings from the Toyota Motor Company. Essentially, it attempts to present Lexus' strategy to penetrate the American luxury car segment and to steal the pie from the Germans (e.g. Mercedes, BMW, Audi) and the American classics (e.g. GM's Cadillac, Chevy, Sature and Ford's Ford, Lincoln).
The first half of the book outlines the creation of Lexus' LS400 and the company's foray into the USA market (i.e. channel strategy, marketing, manufacturing). The second half provides a cursory treatement of their other models (GS, IS, RX, LX, SC ... pretty much in this order) and their plans to enter some other markets (Japan, China, Asia, Germany).
I felt that the book did a reasonably good job of sketching the players (i.e. the Lexus executives) and their respective roles in the shaping the company, designing the vehicles and manufacturing them. However, I thought that the book would have benefited from a more detailed treatment of the Lexus line-up (i.e. the specifications and relative strengths and weaknesses of their vehicles).
On the whole, I enjoyed "Driven" more because of the breadth of coverage - ranging from BMW's rich history to futuristic hybrid vehicles. Also, I somehow had the impression that the book was rather sterile... It was as though the author was writing from afar without opinions or affection for the topic...
I hope this helps!
