After only 6 weeks I'm not able to rate reliability, but based on performance, ride, style, and comfort this car is hard to beat for the money. I would say a clean, well-maintained, and low mileage Cadillac Seville STS is a "Best Buy." It has a 300 hp engine, averages 19.5 mpg in city with 25+ on highway, goes 0-60mph in 6.4-7.0 sec, has heated seats, power sunroof, and leather for $4,788! Unbelievable! This is one of the better handling front wheel drive cars I've driven. For 300 hp, the torque steer isn't that bad.
Sharp looks, American V8, durable/luxury interior, smooth ride/performance, suspension balance, decent handling, acceptable gas mileage, and affordable.
Doors auto-lock when car starts. Obviously, they learned their lesson and have since changed to when the vehicle reaches 10-15mph. It is too easy to lock yourself out.
