My sister had one for a year or two, said the V8 was essential (no power otherwise) and then she got rid of it (gas hog, etc.).
She has a Caravan Town & Country for years prior to that and found it to be a good combo (running to country place with tons of stuff). Country place was sold, so no need. I guess to run around town, she now seems to prefer the sedan.
My wife traded in a Grand Caravan AWD for the Benz. The eight
would be better but to many $$$$ to justify and she finds using
the manual shift mode helps a bit. I still favour my MO but enjoy
driving the Benz considerably more than the van.
