The 2009 STS occupies a slot in between the CTS and DTS in Cadillac's lineup. In terms of performance and features, it is every bit a rival to the top sedans from Germany and Japan. With all-wheel drive, the STS makes a surprisingly good all-weather car, and with its front-wheel steer system, the AWD V8 model is especially safe and nimble. Inside, the STS has a look and feel that entirely justifies the price, plus convenience and safety features that compete with the best in its class.
