In 2005 I leased my 5th (and final) one. I love the car. Comfortable, powerful and classy. But sad to say, Cadillac decided to discontinue the model. I have been driving these cars (SLS and STS)for over 15 years and never had any major problems. Except for normal wear of consumables. My 2005 has never had to be tuned, and continues to run like a dream. That's reliability.
AWESOME Bose 15 speaker sound system! Northstar V-8 power, heated/cooled seats, great looking leather & wood interior. Just a class car.
the ONLY negative is the lack of storage space. Glove compartment is insufficient, center console is small and any cd's use up most of the space.
