The Mercedes-Benz AMG GT has been one of our favorite sports cars since its debut in 2019. What could make it even better? Well, Mercedes seems to think an extra pair of doors. The new 2019 AMG GT 4-Door Coupe doesn't offer S-Class levels of luxury, however. Instead, it trades rear-seat accommodations for a far more engaging driving experience. Of the brand's sporty four-doors, this one is certainly the most performance-oriented.
