For those of you looking form more historical information on the 5 series check out BMW 5 Series The Complete Story by James Taylor. I ordered the book about a month before it was to be released and it came in the mail the other week. I just had a chance to read it over and it had tons of information on the car(s). Including the 5 series from Hartge, Alpina, and Janspeed. It starts off with a little history of BMW before the 5 series then moves all the way to the E39 M5. The book also covers information specific to the US and UK and South Africa.
One warning to those of you who might get this book while waiting for your 5 to be delivered. It just makes the wait that much harder.
