"Bought a used '05 with 13K miles on it for about 20K in October of '06.
Couldn't be happier with my purchase.
Mileage averages 20.5 or so, getting almost 400 miles/tank. Have not had a single problem so far and it drives like an absolute gem. My wife drives a Jeep Grand Cherokee and this truck is immeasurably more reliable.
Back seat isn't the most comfortable, but front seat is fine. Went on a 3500 mile road trip in it and didn't have one complaint at any point.
The SE Model that I bought has the radio controls on the steering wheel, which is a great feature.
If you're looking for luxury, this isn't the truck for you, but if you want reliable, power, get-up-and-go and don't mind a slightly bumpy ride, this is the truck for you. Great value."
"This 06 is my second Xterra, my first one was an 02. I loved my first one, but with a great trade in value and a bigger engine I had to get the upgrade. I have a 6 speed manual and I get decent gas mileage on the interstate about 20mpg going 80-85.
It also has great passing power and I feel safe driving it. I don't think I would own any other type of SUV unless they quit making them."
