Five-year cost to own: $57,153. A lackluster 16/23 mpg (city/highway) fuel economy from its standard 5.3-liter V8 engine help drive up the long-term operating costs for the large and in charge Chevrolet Tahoe. On the other hand, the Tahoe pays owners back with generous interior room, a long list of standard and available amenities, and a beefy tow rating that maxes out at 8,600 lbs. when properly equipped.
