In 5 years of ownership I have not had a single issue regarding drivabiliy or dependablity. For $25,000, a car with a good deal of ammenities. All the ones you'd expect, with the additon of full leather, and the added bonus of a sport suspension. Had driven the non-LS version as a rental, and really liked what Chevrolet did to punch up basically a family sedan.
Overall interior space. Not having the lid arms inside the trunk is a nice feature. The bonus of a car that gets between 29-31 miles to the gallon at 70 miles an hour with A/C on. That's Toyota Camry mileage in a larger automobile.
Where my left arm rest on the drivers door could be a softer material. That's it.
