Regular maintenance costs remain zip, zilch, nada, zero for Cars.com's long-term 2014 Chevrolet Impala test car. We've gone through two rounds of oil changes and tire rotations after 13,808 miles — once at 6,000 miles and the other at 12,000 miles — and Chevrolet's two years/24,000 miles of complimentary maintenance have kept those services freebies so far. That leaves two remaining services before we reach our maximum service frequency (four) of the service plan.

The Impala spent unscheduled time at the dealership after we noticed a dull vibration pulsing through the floorboards and seats above 60 mph. The pulsing was worrisome enough to warrant one editor pulling into a service center during a road trip to have the car inspected.
