While sedan sales continue to decline across the United States, there are a few sedans that continue to make us remember why we love the simplicity of a sedan. One of these perennial best sellers is the CT4 sedan. The mid level trim is the Premium Luxury Trim. The CT4 is one of the best sedans in the market, and continues to make an argument for more sedans. The CT4 is fast, fun and nimble. It has a whole suite of luxury options and is outfitted with a ton of standard options that make the Premium Luxury worth the price tag. This sedan is incredibly well appointed and makes use of powerful engines that bring out the best of the Cadillac in this generous low to the ground 4 door.
