 This is my third Nissan vehicle. Have not had any problems with this 2.5 altima. It has leather seats, moon roof, Bose system. After driving my 92 Nissan truck for years without any problems and my 2000 frontier without any problems, I decided that Nissan was  by far the best, most reliable vehicle I have ever owned. Both pickups are still running today and had 189,000 miles or more on them when I traded them in. This 2006 altima exceeds my expectations everytime I drive it. I knew the engine would be a little bit louder than other cars because of the timing chain instead of a timing belt. But in my opinion makes it more reliable.
