What would be a good price to pay fo a 63 Gulietta Spyder? got a web link?

What kind of condition? A really unique cherry one could be up to 30,000 Euros. The results from a RM auction shows a 1962 giulietta spider results as $18,500. So I hope you have good luck and find a sweet bargain. Maybe a dottering old guy with a amazing barn find will land in your lap.
