If you want an SUV that is easy for your parents to climb into the cabin,then you'll need to look towards monocoque Cross-overs.Tall BOF SUVs(like Safari,Fortuner) indeed are very taxing for old people to climb in.I suggest you go and test drive new CR-V or Chevrolet Captiva and enjoy the best of both worlds:-) You'll get ground clearance of SUV while climbing onto the cabin because of unibody design would be much easy.BTW,even though Aria was BOF crossover,it was the perfect vehicle for your needs,only if the quality of the product was little better with better A.S.S. :(-
