Is there any difference when putting mileage on a 2010 Toyota Sienna?

What is your question?

How big of a difference is it to get a 2010 Toyota Sienna that has 172000 miles on it when over 100000 miles were put on in the first 3 years and had all routine maintenance done at a Toyota Dealership. It was a company car and has had only 1 owner.

What makes this problem better or worse?

Not sure if the high miles should be that big of a concern.
