We bought our 1997 Grand Caravan used with 26500 miles on it from a dealership. We also bought an extended warranty taking it to 6yrs/75k (only used it once for the starter but it was nice to have peace of mind). Overall it's been a pretty good car with only three problems; starter went out at 50k; brakes; wiper goes on for no reason (not covered on extended warranty).
People and cargo capacity
Improve brakes and electronics. Other than that we've been pretty happy with it.
