Overview & Reviews
Not much changes on the 2006 Cadillac STS. Items of note include the availability of all-wheel drive on V6-equipped cars, a standard Bose audio and navigation system as part of the V8 luxury package, and optional 18-inch wheels.
- Full-size car at a midsize price, nimble road feel, powerful engine options, available all-wheel drive, optional Bose stereo is one of the best in its class.
- Sporty bucket seats might be a bit firm for some, plastic interior panels not quite up to German standards, only one transmission available.
