Valley of the Gods is an area near Mexican Hat which is similar but smaller than Monument Valley and has a simple loop drive. I did it in a rental Blazer back in 2004 but saw cars on it too. There was a little "steppy" section which would probably test the clearance of most cars. A great sampling of that type of terrain though and great for pictures.
There are some good guide books on Amazon such as:
The Trails Illustrated/National Geographic maps are good too.
