The Mercedes-AMG GT is a theatrical sports car with prowling looks and an aggressive exhaust note that announces its intentions the moment it fires up. It pairs ferocious performance with surprising everyday usability — a taut yet forgiving chassis and a cockpit that feels special — making sensible buyers suddenly very good at justifying indulgence.
