I've driven my mom's CR-V around the horse pastures and some pretty gross stuff, and it did okay. With better tires it would probably be more competent, but I hate the AWD system in those things. The front has to slip considerably before the rear will help at all. Even then it's very slight so the back end doesn't kick around at all. That car will predictably understeer in every circumstance. It has to - if the back end kicked out, ever, the outside rear wheel could catch and tip the car over.
It doesn't even really have a lot of space inside or get good mileage. It's an okay car, but I'd rather have an Outback and my mom's looking for one.
