Best got from your Fiat dealer.  Speak to them nicely and they will order
you a copy.  They come on CD/DVD these days and are amazingly cheap compared
to the cost of the old series of printed manuals.

Price will be around £15.  I got my Croma 2005 manual for less than £7 inc
vat.

For the Stilo I have Part No:60448084, Pub.No:507182CD02, Printed 01/2002

This has probably been superseded since 2002.
