Sounds like a race car because it once was one.
The Alfa Romeo Giulia Super was one of those magnificent homologation cars that you never hear too much about. Several different versions existed, and although the only really big difference between the Super and the regular Giulia was that it had two carburetters instead of one, this actually made for a small sedan that was faster than quite a few sports car of the day. Of course, this is why it made sense as a race car, and street versions were built for homologation.
The car is obviously quite rare, especially examples that are in as good shape as this one. But we're happy to see this, and possibly even happier to hear it.
