Very true, I have been trying to buy a decent one for 3 years now and no luck. I have an automatic search running on ebay for all 145's within 250 miles of me and in the last 2 years I have had only 1 result and the car was the same spec with the same faults as the one I have on my drive.
In the last 18 months I have not seen any on the road. I have seen a ferrari F50 and a Mclaren P1 but not a single Alfa 145, says it all for rarity.
I very nearly bought a mint one from a member on alfa145.com, jjgrosovner or something. Finally got to the stage of closing the deal and when I said I would buy it, when are you available for my to come down and drive away he seemed to disapear from the face of the earth and to this day hasn't returned (3 years later).
