The Odyssey or Sienna option is for real. Make sure you get one of the heartier equipped models.

A Duramax equipped van would be hard to beat unless it was mistreated and you got stuck with repairs. $$$

Ford E series has been the backbone of many service companies for decades but I am not familiar with modern drivetrains. I have seen some V10s with 300K miles and going strong but I have heard early death horror stories also. Changing plugs on a V10 can kill it or kill your budget. Some powerstrokes run forever but one abusive driver and all bets are off. Power$troke repair$.

Just as trivia, the Mazda MPV made its mark on the automotive world. Evolved into the Mazda 5 which can be a good vehicle.

Old Fords are just about give-a-ways. Someone gave me an 80s E150 years ago and it was a good vehicle. Straight six is tough as nails. Same for C6. E4OD got a bad rep because of the selector switch. Give-a-ways are throw-a-ways.
