This car is far & away the best car I have ever owned, so far so good! The only fault is the speedometer is hard to read in daylight, and the visors have no extensions and I'm told none are available. It's too bad GM had to wait this long to build this type of quality in a car.
Quietness of the ride, seating comfort.
Make the speedometer more readable in daylight. More insulation in the roof/headliner and visor extensions.
