Maserati MC20 Roadster

The Maserati MC20 Roadster is an open-top Italian exotic that pairs razor-sharp handling with a cathedral-like exhaust voice and sculpted, winglike bodywork that stops people in their tracks. It’s for buyers who want rarity and drama in a usable package — a car that looks like gallery art, sounds like a declaration and asks for a confident owner with a generous sense of adventure (and budget).
