As someone's company car, my 2007 eddy was on long life regime from new. The serv book shows it.
I strongly disagree with this approach, but....
Things have changed now, i have posted here already about regular oil changes etc.
As long as there have been additional oil changes, and proof, i wouldn't be too concerned.
There will be lots of other service items that you should be doing immediately, brake fluid, PCV, PRV, fuel filter etc...loads of info on here.
