Yes, I think you first have to get clear about the subject before you can speculate about price.

I like your dream; for me, cars generally symbolize how we are in the world how we conduct ourselves; I'm glad your husband would not take the car back :-) To me it sounds like he either is sticking with himself and his car or that he's not going to leave you. It does sound like you were worried about debt though.

It might just be that you have not quite separated money and yourself. Concentrating on money instead of or at the cost of relationships is not a good idea to me. If you and your husband have been arguing about money and how to spend it instead of focusing on your relationship and what you both really desire and how to get it and working together, the price could be the relationship.
