how many miles should I expect out of a 2013 highlander limited with maintenance kept up?

Worked on a 07 4 Runner last week with 584k (584,000) on the clock, still running like a charm! .. Salesman drives it on the open highway which is easier on one but I thought that was pretty impressive! .. I see similar results from other Toyota models, which is one reason there's 3 of em in the driveway right now! .. I am not saying other makes won't do the same but I am saying exactly what I've seen on a regular basis, for 'SEVERAL' years now.
