Like others have said, mileage isn't everything. Especially the small difference in your example. The new would be better for resale in the future, plus if you are only driving 5k miles a year it should hold that resale value pretty good even starting out with more miles.
My wife has been wanting me to get a newer truck. My old truck is a mid-size 2002 Explorer Sport Trac. I've had it since 2006 or 2007. Has under 160k miles and still runs really well. I've only had a few issues I've had to repair over the years like a busted thermostat housing (common on this engine) and a Mass Airflow component that went bad and affected idling. I also just replaced a wheel bearing in the front that was making a loud whining when driving. That was a $15 repair. Don't get me wrong, it looks like a 21 year old truck, dents, paint chips and the drivers seat has seen better days, but it gets the job done.
My problem is with the price of used vehicles since the chip shortage drove the price of all used trucks especially to the moon. New is not an option, I can't bring myself to buy a new truck that cost almost as much as my house and depreciates instantly.
What I would really like to get is a mid 70 to mid 80 square body Chevy truck short bed preferred. I could probably get a really nicely rebuilt one in the $20k range. And it might actually get more valuable over the years. I'm sure gas mileage would stink, but I don't drive all that much.
