Thanks for the info. It isn't likely I'll get an off rental unit.
I've owned lots of Explorers and would know what to look for if I got a used one.
Just not sure if the XTERRA has some congenital problems I should be looking for. I was a bit concerned about an 05 because it is a change over model year and that usually means first year problems. I owned a first year Pilot and dumped it within 2 years because it had so many problems.
If anyone has any specific problem areas on these vehicles I'd appreciate hearing it.

Thanks again
