I would look at searchtempest.com and expand your search are to at least 600 miles. A 2006-7 Prius should be findable for under 10K. I think they are 10K oil changes, brakes last forever, and mid forties mpg driven like a normal car. Battery problems are rare unlike the Honda hybrids. If this is her commuter car, rent an SUV or whatever for those family trips.
