Regarding the portuguese Alfa 75, driven by Rufino Fontes, it still exists and still features its 1987 livery. It's owned by Fabrica Italiana - TRSport, a portuguese tuner.
This car started life in 1986, as 2.5 V6 Alfa Corse car, and was the development mule for the 1.8 turbo engine for 1987.
Rufino Fontes, who was linked to Alfa Romeo for several years, bought it for the 1987 season, to replace the Imberti GTV6 he had been racing in previous years.
That year, there were two brand new Schnitzer M3 for Petiz and Pequepe, plus the ageing but still competitive Volvo 240 Turbo of António Rodrigues and Artur Mendes, and BMW 635 CSI of Manuel Fernandes and Carlos Rodrigues. It was the best line up we had for years.
Infortunately for Rufino Fontes, the Alfa 75 was never competitive. In his words, the car was fast for a couple of laps but then it seems to melt and the power and handling faded away.

Nevertheless, the car won the last race of 1987, in Estoril. It was an 3h endurance race, extra championship. That was the cars' last race...
I found the car in 2006 and Tomé Coelho, from Fabrica Italiana bought it. It was shown in the Alfanord stand at Interclassico, in October 2006.
