one of kind in texas!! superman style! Breathtakingly expensive, hugely powerful, and anachronistic in looks, the G63 is not for the introverted. With roots going back to 1979, it retains its basic fashionista-meets-Sandinista look. In the G63, a twin-turbo 5.5-liter V-8 makes 563 hp and 561 lb-ft and mates to a seven-speed automatic; all-wheel drive is standard.
