A vehicle with a high step in/out is what you need. Not a climb up like an SUV. A crossover or high wagon Mitsu Outlander, Vibe/Matrix, Mazda5, etc. Also the Chrysler 300 and Magnum have a high step in/out. Big sedans (Lincolns/Mercury’s) often associated with old people usually have a bit of a climb to get up and out. Get a vehicle that doesn’t require up or down movement.
