Extended Warranty
I have a had 97 grand caravan since new in the family fleet. It uses the same 3.8 motor that you may be considering. It has given great utility as the seats can come out when cubic cargo must be moved. Drives good in new england snowstorms. "Rear air" is a must option if you are going to have humans back there.
Now the caviat. We bot it with 100K warranty. Under such, both heads needed servicing, then the motor blew at 98.9K. In my fleet, I have a 209K honda and a 155K toyota with original engines and drivetrain, so I would be pissed to pay for a new motor at merely 100. The steering racks and trannys are suspect, but I haven't had trouble. (These may be the same as in your '01) Check it. Also under warranty, we had horn relay (pricey, don't laugh), and some other on board CPU replaced. When I was shopping for a pick up truck, I was amazed at the number of 70Kish Dakotas with new trans or motors in the want ads.
I'd grade mine a c+, F if I had to buyt those warranty parts, but that is what you are paying for.
