My reserve has 33,000 miles and is as quiet and powerful as the day I bought it. The Lincoln noise cancellation feature is great. I purchased mine as a returned rental model, and it seems to have held up well considering all of the abuse and rough driving a rental car typically gets. Leather seats have help up, handling is still great, and the car looks in showroom condition. If this holds, the MKZ should continue to look good and last a long time!
