RX300....barf.
I would easily pick the VUE redline over it, with the GM Employee pricing now.
Not sure what your mom's budget is but she might want to also check out: Subie Outback, Volvo Cross Country, Audi Allroad (these suckers are expensive new, but comedown pretty quickly in price so a CPO is not a bad deal) or a BMW X3. Prestige BMW in north NJ advertised one in the sunday paper for 27,9xx with a few options. Granted it was a lefotver '04 with 10k on it, but not a bad price (I don't think).
