We have a pretty plain model of Grand Caravan (2003). It has two bench seats, and I wish we had captain's chairs instead. It also doesn't have self-closing doors. It's funny to see the teachers at the school drop-off zone. They just assume that they close themselves, and are baffled when they don't. I really don't miss having them, but maybe they'd be nice. I worry about fancy features because more is likely to go wrong.
We had our brakes go out last month, and there's an oil leak. But it's 8 years old, so those aren't unexpected issues. Also, we have an oil pressure light that comes on and "dings" when it's cold, but it's not an actual problem, so we just live with it.
I love all the space, especially with all the seats out. I moved an 8 ft couch in it with the tailgate shut. Another time, with the middle bench seat in, with two kids riding on it, I fit two wicker love seats, a wicker ottoman, and a wicker chair in there! Crazy amounts of room. It's great.
Oh, and we bought the van with 90K miles. We're now up to 120K, I think.
One thing I HATE about my van is the locks. It has power locks, but no clicker key fob. We tried to buy one, but our particular van is not equipped (like the sellers told us it was. ARG!) They lock automatically when you hit 20 mph, and you can't unlock all the doors with the key (with my first car, a 1998 Camry, you could just turn the key two times and all the doors would unlock. Same with my Altima and my Jeep). So I unlock one door, open it, use the power lock on it to unlock the rest of the doors, and then we can get in. This is a pain with two kids and a baby and all the stuff that comes with them. We've gotten used to it, eventually, but go for a clicker!
