Yeah, maybe someone will actually be helpful.
Yes, on your own, see what the dealerships return policy is, some are even as much as 30 day return for money back or exchange and than if possible, encourage them to get into a more affordable sedan that has a good build quality, reliability record and a less abrasive financing situation; monthly payments, insurance, upkeep and repairs. Sometimes there is no return policy and that's usually on cheaper vehicles and this one is probably going to have some recourse if the time has not expired.
Many of us have bought cars that are beyond our abilities to repair and maintain. I would recommend to someone needing financing to go pick from the older 4 door sedans with low mileage if buying from a buy-here-pay-here lot. Teaching them how to check the fluids and tire pressure may also help them develop an interest in doing some of their own repairs, a small OBD2 code reader for a gift may also be a inspiration.
Newer, used cars that are out of warranty could become a big expense. If you can't get the maintenance history one very may be getting into vehicles with high mileage oil change intervals and sealed transmission that should have scheduled maintenance. If I recall right, some manufacturers has a 10k oil chance interval after about 2010, I'd look for something with a 5k interval, not sure what Honda's is.
I'd venture that a 129k Odyssey and a 73k Pilot aren't far enough apart in mileage that either one is that much better than the other. That Odyssey is said to be the Cadillac of minivans and I'd pick that over the smaller cargo space of an SUV, more bang for the buck including tire cost and gas mileage, that's just me, I am not able to evaluate these vehicles for making that choice.
I was only on page 2 when posting this and the subject is up to page 9 so I've still got a lot of catch-up and if I can think of anything more that is helpful I'll get back here.
Honda and Toyota quality levels have dropped over the years,
My thought is vehicles are more complex and more delicately built.
