Want to buy 2002 Chrysler Town and Country

I bought a Caravan new in '92, it was a 93. I think we drove it til '97 when we sold it to our daughter. Shortly after that we bought a '90 Voyager that had 154k miles on it. We kept it 2 or 3 years and sold it to some friends who moved to N. Carolina. I don’t remember having any problems with either car. I now have a '96 Dodge 2500 van that I bought new and plan to keep it another few years. However, it is leaking motor oil and one of these days I am going to take the “dog house” off and check. I suspect it is the oil pressure sender unit leaking.
