16 city/21 highway. Buy it only if you can afford it with out complaining. see full Cadillac STS review

This car is thirsty. I live in flat country and I get 15 mpg with 80% highway traffic. I only get 19 mpg on trips. It probably needs a 6th speed overdive for the highway. see full Cadillac STS review
