The Cadillac STS is a great road car. Fuel mileage (overall) 21 mpg but engine not yet broken in with 1,000 miles. Leather seats could be softer but quality is good. Only dissatisfaction is with glove box which is rediculously designed and much too small. Good storage between seats helps. Previous 3 cars were Acura TLs which were great cars, but just as satisfied with STS.
Re-design the glove box and they have a perfect automobile.
