Sapele Wood Trim Package (Heated Steering Wheel), Light Gray w/Nuance Leather Seating Surfaces, Inside Rear-View Auto-Dimming Mirror w/OnStar Ctrls, and Preferred Equipment Group 1SA. Cadillac has outdone itself with this outstanding 2008 Cadillac STS. It just doesn't get any better at this price! All work and no play makes Jack a dull boy. Well Jack was never accused of being dull in this STS. As a matter of fact, Jack has a little bad streak. And speaking of streaks, looks like he just left a couple more leaving the last stoplight. It scored the top rating in the IIHS frontal offset test.
