Dutch manufacturer, Savage, has been hard at work the past couple of years working on their 4-door \"topless on demand\" supercar, the Rivale Roadyacht GTS. The first prototype version was released back in 2008 with a production model envisioned for 2009. Now, two years after the planned debut, Savage has finished their unique supercar and will be debuting it at the Top Marques Monaco, starting April 14, 2011. The Rivale Roadyacht GTS is the result of the wild imagination of three men who believe that every dream should come true. Their dream turned out to be a limited edition supercar with only 20 units and in only three exterior colors. According to Savage this will be the only 4 door \"topless on demand\" supercar in the world. It combines a \"bad-boy\" exterior design aspect with an interior inspired by the yachting world. With a 670 HP V8 engine under the hood, the Rivale Roadyacht GTS will be capable of sprinting from 0 to 60 mph in 3.4 seconds, while top speed goes up to an impressive 205 mph.
