 Only had the truck for 2 weeks, so can't comment on reliability. Had an 05 Colorado CC Z71 2WD(poor mileage, jolting ride) an 08 Frontier V6 ext cab(very poor mileage). Got the XLT for the options and the 2.3/5M for mileage. Am very pleased with the ride(much better than Colorado/not quite as good as Frontier)Fit and finish are as good as previous trucks. Brakes(4 wheel disc) are on par with others. Power and acceleration are down from others, but is acceptable.The mileage is light years ahead of others, about 10 MPG better than both previous city and highway.  I only tow light loads(flat boat/utility tlr), eng. easily handles    Based on build quality, ride, mileage. I highly recommend
