I picked up some husky liners for the front and rear seating areas today.
They fit pretty good and will fit better with time as they flayen out after beong crunched in a box for who knows how long.
For the 2000 and 2001 Xterras there is a little bit of trimming required as the cupholders are in the way. They were changed in 2002 with the redesign.
I wanted the digital fit weather tech mats but unfortunately they don't make them for the first generation. These will do me more than fine and keep the crap on the mat.
I got the grey which matches the interior nicely. It isn't as dark as I thought but still good.
