When is high mileage on a late model a concern for purchasing?

Hey guys! New to the forum and new to Tundras in general. We have a 2015 Highlander and I've started to get the truck bug, so I've been looking into picking up an SR5 CrewMax. Brand new is out of the budget for the time being, even if there's not much of a disparity between used and new at this point. However, I came across a 2017 SR5 CM w/ TRD Off-road and SR5 upgrade packages. Downside is that it has 80k miles, at an average of 35k/year since it was originally sold. Our highlander had an average of 25k/year when we bought it, so this isn't terrible far off. But I wanted to see your guys' thoughts on something like this. Obviously if it has solid maintenance records I could sleep better at night, but even my wife is concerned about that high of miles. Kicker is that they've got it listed for $28k or $29.5k depending on where you look. I figure I might be able to talk them down a little bit more since it's been on the lot for 51 days, and get a hell of a steal on a 2 year old truck. What are your guys thoughts? Thanks! Here's the listing for reference:
