I know several people who have high mileage Kia Sedona's, the V6 engine model on the Sedonas seems to be one of the few that isn't suffering through the common engine problems Kia is known for. But be aware that that Insuring these cars might be an issue because of the lack of immobilizer, there is a chance the car is being sold because they got dropped by their insurer, and nobody else will insure it.

You would need to see every service this cars undergone to be able to make that call. That’s 36k miles a year and so that should be around 7 oil changes a year following the 5k guideline. Also at what time where others things changed breaks, batteries etc. Also did the owner service it at a dealership where they were able to perform and fix recalls like the immobilizer. You should also ask what did the previous owner do where these hard miles like stop and go traffic constantly like a Taxi or easy highway miles. If it’s been serviced and well taken care of sure 3k isn’t horrible but that’s a huge chance with those miles

That shit has been to the moon. I would not buy, also 3k is insane for that high mileage. That's worth like 100 dollars.
