The interesting part of the off-road stuff is that the rule is actually "Vehicle shall not be driven on an unpaved road or off-road." To be honest, there's areas of the country that there's enough dirt roads around that I find it hard to believe that anyone pays any attention to the unpaved road portion of that. And at that point, the question then becomes a semantic one of what's an unpaved road and what's off-road?

So is everyone here honestly going to say they've never taken a rental car down a dirt road? I suspect the largest repercussion of doing this would be that if you had purchased insurance from them that they'd deny it. Whether your own insurance might pay for anything might be debateable too if you hadn't purchased insurance. If you break down in the middle of nowhere with one, I wouldn't exactly rely on the rental car company coming to the rescue for you.
Also, these days, Wranglers seem to have developed a following amongst certain segments of the population that I wouldn't necessarily say intersects much with the folks that would use one off-road. I'm honestly not sure *why* they've gotten popular in the segments they are, but it seems to be true.
Personally, I don't really find them that great as a vehicle for driving highways on. It's been a few years from when I last rented one, but I always felt the short wheel base made them prone to being difficult to keep in a straight line. I'm pretty sure the motor's been updated since the last one I rented, but at the time, it definitely wasn't a great one, and gas mileage wasn't great. I think the ones with the current 6 cylinder are a lot better than they used to be. But if you're not doing a lot of long distance highway driving, I don't find them to be that bad. Not great if you need a lot of luggage space though.
Pretty sure anything I may or may not have done with a Wrangler in the past should be well past the statue of limitations on things

.
Now that's honestly a vehicle that I can't comprehend. I've driven them, and there's enough roll in them to make one sea sick. Hopefully the new generation ones fix some of those issues, but last time I had one as a rental (which may or may not have also gotten dirt on the tires), I wasn't real sorry to turn it in at the end. Personally, I'll take a nice grand cherokee over a 4runner any day. Unfortunately, these days Stellantis has moved so many of the features on GC's to the upper trim levels, so while it used to be you could get a Limited that was equiped well, they're just not as nice at that level as they used to be, and I suspect finding higher trims isn't real likely on a rental lot.
