I've been thinking about your excellent answer and have a follow-up: I am not confident that the car is is worth putting much money into it-which even replacing just the oil pump is expected to be near $1000- and the trade-in value would probably be not much more than $1000, so I'm thinking it would be best to just run the car as is and just use it around town. I'd expect to put no more than a hundred miles on it every two weeks. Does this sound reasonable to you? Could I reasonably expect the car to be usable for several months and when it fails what will happen-- I don't want to create a safety issue? I realize you can't offer a definitive answer, just looking for your opinion on the matter.
Thank you so much. You've been very helpful and I will be following your advice. And your opinion of the Sebring is spot on- the worst car I ever owned and that's coming from someone who once drove a Rambler and a Karmen Gia.
