Thanks to all for these wonderful suggestions. No, I did not abandon the thread, I honestly didn't think there would be so much response in so short a time so gave it a couple of days. I also had a challenge trying to get back to this thread. Now that I recall the exact title, it should be easier.
I am a self-employed CPA fresh off a horrendous tax season and spend a good bit of time on a tax listserv with other practitioners. There are all those extensions in my pile staring at me now, too.
I really like the Forester idea and, generally, the small SUV. It will be easy to check a Forester as another person at church has one we can test for ease of entry and exit. I also like the "Measure butt height" suggestion but that might be a bit intrusive. These folks are not my family.
Thanks again for the great responses. I will try as many as practicable and let you all know, although it may be several days.
