True American Muscle-Cars

@Spa-Italia, I saw these two American Muscle Cars : The Dodge Viper GTS and a Corvette C6 Convertible.
The Dodge Viper GTS has the famous "Dubble Bubble"-roof. (As seen on the legendary Zagato-models). This allows the usage of helmets.
The engine is a 8l. V10! Yes, 8l... those crazy Americans...
It produces 450hp. and has a topspeed of 306km/h. (0-100 in 4,3sec.)
The Corvette C6 has a 6l. V8-engine with 400hp, a topspeed of 300km/h. (0-100km/h in 4.3sec.)
