2016 Impala Limited worth buying?

What are your opinions of the Impala Limited, the last of the W-bodies?

Are the 3.6 Litre V6 and 6 speed transmission good? Any achillies heels or other quirks with these cars I need to look out for? Are these Impalas easy to work on?

Pretty reliable car, no real "issues". Keep the oil changed to help prevent cam actuator problems. Get the rear suspension aligned, the W cars are notorious for too much negative camber, causing tire wear. They are great road trip cars.
