Not very many complaints about the 06 Frontier. It is a little pricey compared to the competition and the gas mileage isn't the best but it is a great truck to drive and can handle any weather thrown at it. There were a few rattles and vibrations when you drive on rougher roads but nothing that would stop me from buying another one. I could use a little more head room too. I would definitely recommend it to anyone who is the market for a tough mid-sized truck.
