The 2008 Cadillac STS, part of the first-generation STS lineup, is a luxury midsize sedan known for its robust engine options, comfortable ride, and stylish cabin. Engine choices include a 3.6L V6 that produces 302 hp or a V8 delivering a hearty 320 hp, mated to either a 6-speed automatic transmission. It’s available in three trims: V6, V6 Luxury, and V8, each getting progressively more upscale in terms of features. All models are rear-wheel drive, but an all-wheel-drive option is available. Inside, the STS offers an 8” touchscreen navigation system and a 15-speaker Bose Surround Sound system. Safety equipment includes anti-lock brakes, stability control, and six airbags, but lacks the more advanced driver assist features found in contemporary rivals.
