Just getting caught up on the Grampa Car Drama! Very exciting.
Can confirm grandpa joke is on point: my 86 year-old dad is a grandpa many times over, and has had a succession of Camrys from the late 80's culminating in his current 2006 that looks just like yours.
He has no interest in ever progressing past this body style. If one day his current car needs to be replaced, I'm going to have to look for another low kilometers 2006 just like last time.
Fortunately, so many old folks buy these cars, it's really not hard to find low kilometers examples. A 90-something year-old friend of the family has an '05 Camry with about 50k km on it (~30k miles).
Of possible interest:
