Umm........, uhhh.......,
Dodge Caravans are not GM vehicles.
Those would be Daimler-Chryslers, but glad to hear that they have served you well. Most Domestic cars and trucks are OK for the first 100k miles if maintained on schedule, regardless of make.
FWIW, I own a '99 Taurus wagon w/ 130k on the clock that has been ultra-reliable, (knock on wood).
