I partially agree, because like it was said, the 430 Scuderia has that sex appeal that all Ferraris should have
the Challenge Stradale also has it, and before that, the F355 had it, and before that many many others
I guess it is just that they don't "do the magic" in all of their cars, so in the current line up you have a Ferrari that gives you the "WOW, it's a Ferrari feeling" (the Scuderia), but you have Ferraris that are "just" great, but nothing else.
It is like that now and it was like that in the past. Not all Ferraris from the past have that "WOW" thing about them.
