The Spanish auto manufacturer a.d. Tramontana showed off its flagship model at the recent 2007 International Motor Show held at the Palexpo in Geneva, Switzerland. This aerodynamic baby packs a punch with twin-turbo V12 that can produce up to 720hp, just about as powerful as an F1 race car. Everything inside is pain-stakingly handcrafted, such that the company will sell only 12 of these annually at $900,000 a pop. The a.d. Tramontana boasts a monocoque, 100% carbon fiber frame, while exotic leathers, 8 kinds of treated wood, gold, platinum and titanium were used in interiors and finishings.
