Hi again,finally found that book, ready here we go:
www.bojar-tuning.pl i can only get the site to work in polish but still interesting pictures to look at (F50, F355, Murc) I really like the look of the murc.
http://www.sefap.net/ spainish site a convertible F40, don't really like the windscreen!
http://speed356.tripod.com/classicars/ F40 which looks ok although not a lot of details about it on the site. (watch for pop ups!!!)
This one is great!! http://www.f40.co.nz/f40/index.htm this car was in some of the kitcar magazines and talk around the watercooler is that it is possible to get some part for this car an repeat Steve's efforts.
Sadly I have to say a number of the companies no long seem to be around but try you luck in a search engine you might get lucky.
Autos Prototipo www.raffago.com makes/made ?? F308, F328, F355, F40, F512 and Lam diablo.
hope this was of help to you,
-Steffen
