I bought my truck new and I loved the first time I test drove it. It now has over 40,000 miles on it, and with a little soap, it would look brand new. I have never had a single problem with it, especially with the engine. The engine runs as if I just bought it yesterday, probably due to the exceptional engineering by Nissan's engineers. I knew a guy who had many Nissan truck's go over 400,000 miles still running good, and I know mine will do that good. The 4-wheel drive also works very good. The only bad thing about the 4-wheel drive is it has a manual locks on the wheels so you have to get out to engage the 4-wheel drive. Also, the acceleration on the truck is a little slow. Great Truck though!
