Love the Avalon.
In Arizona, you have some advantages others don't have. Lots of older folks love the Avalon, and its kissing cousin the Lexus ES.
It is about patience, and maybe friendship. I would wait for a estate selling their Avalon or ES, along with a new car trade in at Bell Lexus or like Toyota dealership. Bring the used car sales manager lunch every few weeks. Let him know exactly what you are looking for "retired persons low mileage AZ owner trade in". Patience is key, if you get it right you can hit a grand slam.
I know the Avalon is discontinued, but if I had to buy a brand-new sedan immediately - the Avalon would be, without reservation #1 on my list.
