Wife and I just bought another 2000 SE 4x4.
Do I have to say anymore?

1st one has 80,000 this one has 52,000.
The one with 80,000 has cracked exhaust manifold been that way for along time, I'll get it fixed one day.

Pretty heavy on gas in the city around 16-17 mpg Ive seen 20.2 mpg on the interstate running 70 mph

I love nissan and toyota but I buy nissan because the nissan's are cheaper for the same thing.
Resale is better on the toyota's but I dont care for resale as I hope to have both Xterra's for 10 years or so.

Towed a 3000 lb boat no problem keep the O/D off in the hills and you should be good to go.

Neither of them are perfect but they get the job done and for family with dogs and stuff they cant be beat.
