@ dretceterini; as mentioned in one of my earlier posts Gila was forbidden to keep on making the Ferrari version of the Alfa 800A transporter. Only very few were made when the production was forbidden. If you find one you have a rare item.
Gila Modelli (not the same as Gulp Modelli) has a website;
Gilamodelli Sas
On this site you will find his range of model cars. The Scuderia Marzotto one is not available anymore, but he might still have one lying around somewhere. A very friendly and knowledgeable Italian specialised in trucks/buses
