I heard that the problem getting info on cars seems more directed at fuel injected cars of the 1980s and later. It seems it was Ferrari's policy to provide Colours Certificates only to owners of carbed cars from 1980 and older. Some how I got by and got one for my 328GTS as did another owner I know. I wanted some additional information and someone from the Classiche Department emailed it to me. But I wanted a written document stating the information I was seeking. To obtain the information in a written document to go with my other paperwork it cost me $250 USD. But I've heard now its $500, not sure if thats because of a weak US dollar or just a general price increase.
