I purchased my Grand Caravan used, from a dealership. It had almost 36,000 miles on it, and the extended dealer warranty was added for me. Considering that it was only a year and a half old at the time, I suppose it would be considered high mileage. However, everything works perfectly, and I would definitely purchase another one! There were a few cosmetic blemishes on the exterior, but the working order of the minivan is exceptional.
