Argot Navis

I'm reading a book by Robert Ludlum (yes, intentionally, jerks) called The Gemini Contenders. It's set in late 1939 and early 1940, and involves Greek priests, fascists, Nazis, communists, British secret agents and wealthy Italians (and I'm only in the seventh chapter). I have several problems with it, though (aside from it being a Robert Ludlum book, jerks). One of the big ones involves a car that the main character (with the assistance of several MI6 agents) steals. It's a taxi, which the main character explains is a Fiat with a “Lamborgini” engine. Now, here's my problem. First, it's spelled “Lamborghini” and second, Ferruccio Lamborghini did not begin manufacturing tractors until after World War II. Not too big of an error there, I guess, except that his car business began in 1963, over two decades after this book takes place. So, I guess we have three options. 1) Robert Ludlum should not write about cars, 2) This book takes place in an alternate universe where Enzo Ferrari insulted Lamborghini's ability to drive a car (while complimenting his tractor driving ability) some time before 1939 (at least eight years before Ferrari began manufacturing road cars), 3) Ludlum is referring to a fictional car manufacturer, Lamborgini. It's an odd error, considering the rest of the sports cars mentioned in the book are, you know, not terribly anachronistic.
