> You can't find a sport sedan to be better than a Ferrari.

"Better" is a subjective term. A sport sedan is better than a Ferrari if what you need is a sport sedan. A different sportscar may be better than a Ferrari if what you want is something that requires less maintenance (or so I hear, I know nothing about sportscars.)

I doubt that anyone who can buy/wants a Ferrari is choosing between it and a sports sedan (M series, AMG series, RS series etc.). It is between Mclaren/Lamborghini/Ferrari and which one is the best depends on personal preference really (looks, are you going to track etc.).
