I used to drive the 57SC Gangloff Coupé sometimes. Whereas it is a stunningly beautiful car to look at, it was rather disappointing to drive. It is supposed to have 200BHP and if so, they must be miniature shetland ponies. The steering is very heavy and the whole car is just a bit disappointing to drive. For a supercharged 3.3L car, the power is surprisingly peaky. In comparison to say a Zagato bodied Alfa 8C2600, which I also get to drive from time to time, the Alfa feels light years ahead in both performance and driving pleasure.
