Well, here we go again ! It's called an Alfa Romeo Barchetta (now there's a surprise !) and it was built by Nestor Salerno in Argentina. Power is by an Alfa Romeo 2000GTV motor, I believe from 1968, because that's the date attributed to the car on some sites. However Salerno didn't set up the recreation business until the 80s, so this car was built after that. The car was in an auction at Artcurial, and it appears yet again to be an attempt to flog a "recreation" in Europe, although this time the auction house was quite clear about the provenance.
Do you need an exact date of manufacture?
