Five-year cost to own: $42,120. With sales of full-size cars fading fast, the Chevrolet Impala may not remain in the automaker’s lineup beyond its current generation. Still, it’s nicely designed, with a cozy/comfy interior, and decent (though hardly stirring) performance. It’s reasonably low ownership costs would be cheaper yet if not for the Impala’s steep dive in depreciation – KBB estimates it will lose around 77% of its original value after five years.
