So I'm a bit mad about Elise memorobilia, before having even sat in the darn thing, and to add to the madness, I've taken delivery of Lotus Elise - The Official Story
by Jeremy Walton (ordered from www.amazon.co.uk
a couple weeks ago).
Lots of good info & pictures from design process of the S1 through the S2 (with info through most of 2002), chassis development, interviews with designers, Lotus in racing, and a bunch of other neat stuff.
Highly recommended for the like-minded Elise obsessed.
