2008 Cadillac STS Review

High output engines performance transmission and rear wheel or all wheel drive. No compromises were accepted designing the 2008Cadillac STS and none will be given. Propelled by either a 3.6 liter Dual over Head CamV6 engine with 255 Horse Power or Cadillac’s robust Northstar 4.6 liter DOHC V8 SFI engine with 320 Horse Power. STS combines its interior spaciousness with lavish attention to the finest detail. The plush materials precise fit and finish and intuitive technology work in concert to create a truly luxurious experience. The entertainment systems in STS were designed to surround you with high quality sound. An encompassing pleasure of sound in a world of performance and style. To coddle you even more STS offers intuitive technology that recognizes you remembers your personal preferences and responds to your voice commands. It’s your performance sedan just the way you like it. The 2008 Cadillac STS it’s the car you are ready for.
