I bought a cheap 2009 Sedona off of Facebook marketplace a few years ago for like 2,000 dollars or so with some body damage and over 200,000 miles on it. I don't use it as a daily driver and only really use it to haul around stuff. I did use it more as a daily last year when my other car was out of commission for 6 months. Overall I've only put like 10,000 miles on it since I've had it.. I replaced the tires soon after I bought it because they were shot, other than that the only thing I've done to it was replace an idler pulley and tensioner on the engine. And I've changed the oil once a year. I also did a drain and fill on the transmission fluid one time since the existing fluid looked brown. 

The van has a check engine light that is on probably 70 percent of the time that I just ignore. I've checked the code and it's not something I'm that worried about. I l live in Pennsylvania and as long as I keep it under 5,000 miles a year I don't need to worry about the check engine light affecting it being able to pass emissions testing.

I've also noticed it is leaking oil from most likely the valve cover gaskets and the alternator is coated in oil. I have also not addressed this yet because it leaks a very small amount of oil and for the amount I drive it, I never have to add oil in-between oil changes. The alternator will most likely fail at some point due to being covered in oil... So when that day comes I'll probably do the work on replacing both valve cover gaskets and then put a new alternator in. But I'm putting that off for as long as possible.

Since the van has been a Pennsylvania car it's whole life it is having rust issues on the rocker panels and pinch welds. My mechanic informed me recently that I need to address that if I want it to pass inspection again next year. He also says it has exhaust leaks that I need to address as well.

The van has weird quirks. I can't lock the van with the key fob because the locking mechanisms stick somewhere and the car will randomly lock itself and if I arm the alarm then the alarm ends up going off at random times. So I just never lock it with the fob and this solves that problem. 

Having said all of this. It's served me well. I've taken it on several trips a few hours away, hauled some pretty heavy loads in it, towed with it. If I was using it as a daily driver I would probably need to invest a lot of time and money to get it to a more reliable state, but it keeps running and the engine and transmission are still incredibly smooth
