By 1988 it was all over- the turbo equivalency factor changed from 1.4 to 1.7 over the off-season, which would have pushed the 75 Turbo into the 'big' class against the RS500s.
Development for the national series in Italy continued, with a series of progressively wilder versions being campaigned until the 155 appeared in the early 90's....

For the final season of the ETCC though, Alfa were out of the game...
....except, for some reason, former BMW team CiBiEmme fielded a single Alfa 75 at Spa- a V6, but in 3-litre form, pushing it into the top class, rather than the original 2.5 litre....

Despite a strong driver squad (Cecotto, Larini, Francia) it was well off the pace and didn't finish.
Jon Dooley also turned out for a couple of late-season BTCC rounds with his former ARDT car- again I think in 3-litre V6 form?
That's the basic history- what else can we fill in? Does anyone know the background behind the end of the WTCC campaign?
I know the 75 was campaigned in other series apart from those mentioned, but who and where? (I've seen a pic of a Portuguese 75 Turbo recently).
Taking a light diversion from the circuits, I think the Rothmans-backed French rally programme with Yves Loubet etc continued when the 75 replaced the GTV6.
I know very little about the post-1987 cars raced in Italy, other than a few pics I've seen. What else is out there?
