When Denice first saw the Xterra's...she had to have one.  We bought ours in the summer of 2000.
This is an idea of where it's been so far as of May 2007:
* 152,000 miles                 * 8 U.S. Sates and 3 European countries
* 48 oil changes                *  No body damage other than some minor dents from a hurricane
* Third set of tires         *   No problems at all.  It runs great!!!
   This has been one Hell of a truck!!!
Some of the places it's been:
Virginia,  Tennessee,   Kentucky,  Georgia,  Washington D.C.
Naples, Rome, Florence, and Venice Italy.  The mountians of Tuscany

A pioneer unit wired up to a set of Infinity front speakers, Sony Explodes in the back and a MTX 300 Watt powered  sub absolutely make it rumble.
