"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."
"great car all around. one flaw, rear suspension weak and needs improvement. bottoms out with the smallest load or no load for that matter. timbren and airlift will fix the problem. great power and simplicity. autotrac is outstanding in snow and ice"
"Solid ride and comfortable driver and front passenger seats". Great power and acceleration when needed....plus 5,000 lb. towing capabilty Good gas mileage if you keep the rpm'S down...17-19 city and 22+ hwy...Nice stying and very utilitarian with roof rack and non-painted bumpers (avoids chips and scratches) Also, VQ engine with DOHC and 5 sp.auto transmission are outstanding."
"I owned an '03 4x4 X and now have an '06 4x4 X. More power and a little better feel is why I upgraded. I have taken both X's all over the US and neither failed me. From the snow to the sand and mud the X is very solid, all factory no upgrades on the '03 and I did get better tires for the '06. Wrangler SilentArmor tires, They have little wear after about 28k. Worth the extra cash for the tire upgrade."
"I bought the 2006 xterra in December 2006 so I got a good deal on it. In the past 12 months i have been impressed by the overall vehicle, reliability, on and off road ability. Having done over 40000 miles this year i have noticed its thirst for gas but with 260 bhp there is a lot of power to feed. With some sensible driving it can be made a lot more reasonable. I am a little disappointed with the paint finish, it easily picks up stone chips..
Overall compared to its closest rivals i am impressed that the Xterra can hold its own in this group of SUV's."
