8 years and still going strong. I use my Frontier for towing a motorcycle trailer and it does fine. Not any reliability problems except my A/C compressor is a bit noisy when it kicks on at highway speed. Nice and cold though. It has held up well in the body and interior department as well. The 2.4l 4 banger with the 5 speed is adequate but won't win any drag races. The gas mileage is great. Even with a raised topper, I get 25 and without the topper I average 26-28 on the highway. The ride is a bit stiff but it is a truck after all. Overall I am very satisfied and plan to keep it a LONG time.
simplicity and lack of clutter under the hood. interior and exterior style. reliability and gas mileage.
class III hitch and trailer wiring should be standard.
