Michael, you have explained a lot. Regarding the Subaru, most of my knowledge and observance goes back to my 2004 and 2007 trips, especially the trip up to AK in 2004. I saw an unbelievable number of Subarus on that trip. And they were all badged Outback.
When I got my Outback I noticed that it was quite a bit higher/taller than my daughter-in-law's in Boston. It was more like the Liberty. And yes, the Liberty is a sedan and station wagon but at home I have never seen the hatch back. Your explanation makes perfect sense. Why do car makers have to make it so complicated?
On the other hand, the Yaris with which I am familiar is nothing like the picture posted by Donna. It is more like a Forrester.
