Oh jeez, I've gotten stuck in my 240z more times than I can count, ironically it only happens when my longtime girlfreind is in the car. The worst was probably in Oklahoma in between Oak city and Lawton on a desolate stretch of freeway. The car ran fine, every day, the whole way from WA to OK. As soon as my girlfreind flies in to see me it decides to go on the fritz. It just stopped, at 60mph on a 70mile stretch of road with nobody around. I spent a couple hours trying to figure it out and finally ruled it down to the ignition coil. Fortunately I'd been doing some ignition work that week and had an extra coil in the back, swapped it out and it ran fine all the way back to Altus. The Z hates the girlfreind.

The Xterra I haven't gotten stuck.... yet. Almost rolled it once though on a muddy dirt road. It was running fine until I hit a point that had a nasty incline to the left and for some reason the mud turned into wet clay. No traction whatsoever. The car just slid into the ditch on the left and leaned friggen hard! I was able to work down the ditch and get the car out onto a dryer section of road. The bad news was that I had to backtrack over the same section. This time I hit it going about thirty and slid the sucker with all 4 wheels spinning for about 100 feet to get through the clay and back to the mud. Scared the crap out of me I thought I was going to be spending the night on my side in the ditch.
