I'm all in DIY if its replacing parts or maintenance. I'm sure I could spend a $1k in parts the first month. Not including a set of Sumitomo HTR A/S P03s (had to throw that in there, lol)I should have been clearer.
For me and my personal calculus, market value and what I think is "worth it" are two different things, especially with the price increases in the last 12 months. That doesn't make this a bad deal - it just means that there are people that will pay more for an old Pilot than I would.
I think that the odds of getting 50k miles from this vehicle without significant incremental investment are pretty low. All of the "look out for this" posts in this thread point out some of the ways that can happen. As NailGrease already suggested, if the OP isn't doing the work, that money might be better spent elsewhere.
There's a lot of cars out there in the $5k - $10k range. For me, a high-mileage '07 from snow country for $5,500 doesn't make the cut, unless the records show that it's been exceptionally well-maintained (motor mounts, suspension refresh, etc.). Others will see it differently - that's what makes the forum interesting.
But ya, I don't do rust.
