Certainly a 10+ year old van will be heavily dependant on the maintenance it received - but if I had to bet I'd go for the Chevrolet for drivetrain. I have more than a few friends who have gotten 200K+ out of their Dodges with no probs - actually mine is a 98 with 100k miles and it has been the most reliable vehicle I have ever owned: only $60 in two small repairs (not counting oil changes, one set of front pads, and 1 set of plugs). mine is heavily over-engineered (huge transmission cooler from the factory, dual piston brake calipers, dual air filter) but in general I would not bet on a dodge....
