My Xterra has 94,000 miles on it.
I've kept up with all required/suggested maintenance and inspections. The only thing I had to replace were the tires at 40,000 miles and they are due to be replaced again. No problems whatsoever.
Sturdy and Reliable:
I've run over a few boulders, hit a few pigeons and side swiped a trash can or two (on accident of course); she takes a licking and keeps on ticking.
The gas bill is a huge bummer, $5,000/year and gas prices are only going up.
