well, i guess we all have different road ideas. i consider that a great dirt road, it's graded and graveled part of the way. as somebody said, if there's been lots of rain the clay gets super slick but that could give 4WD trouble until it dries out a little too. if the arroyo crossings ran, it could also get pretty rough but so far it's always been quite smooth for us. maybe just lucky but we've taken an old, low, loaded honda civic, non-outback subarus, and a 1993 tercel (not the 4WD version) through there no problem. you just don't get in a hurry and navigate around what you don't like. we never dragged butt with any of those.
we last drove it in June and it was fine.
your mileage may vary!
