A decent car, no doubt - a popular rental. But, I'm shocked with the mileage. I'm sure you got it checked out, because it's very rare to see a mini van with such high mileage. Because there are so many minivans in the market, high mileage minivans usually get sold for parts.
ChaterAli, a 1999 Montana's very cheap, especially with the very high mileage this car has. I'm not sure you were around in Montreal when the minivan craze started, but the market is flooded with them now. This one would cost no more than 4,000USD. Even less, at around 3,500USD if bought privately. For half that mileage, inflate the cost to no more than 7,000USD.
Portage will be the first to admit american minivans are cheap, there are just too many of them on used car lots.
