Is it possible to fit a Volkswagen Polo Webasto sunroof (sliding) in to a FIAT.

Why would you do that? Better buy Stilo with panoramic roof... Or if you want find electric panorama roof from Stilo, that would look even better.

It is to put in a Tipo classic and I am going to Italy for 6 months. Nice to have a breas and the sun on my head.

Sounds nice can we come? It depends whether you are fitting the window panel or a complete assembly. The original Tipo sunroof equipment is I believe Webasto-supplied kit and perhaps Webasto supplied the same kit to others. However to create a complete tilt and slide sunroof installation from scratch if you don't have a sunroof would be a *huge* job.
