As long as you like the car I suspect your in good shape to keep it going for many years. As the owner of an AMC that Dodge has not supported appreciably, I can say that a number of other sources will spring up to help you keep the car running most likely for another 30 years if you wish. If you are looking to change cars though an end of the chrysler brand will be bad news for you as it will likely drop price rapidly at least in the short term. As long as you like your vehicle I don't think you made a mistake. If you are not loving it, though, it may be a good time to look at what you would like to replace it with while it retains some value
