In the end IMO it comes down to the real value of the cart, your willingness to put up with hassle and do not forget the advertising cost of the paper. I could be mistaken but I thought it was $70/week...
I guess at a minimum for peace of mind, I would call one of the people who advertise in the paper that "they will buy your cart no matter the condition". Obviously they will be a low ball number but will give you an idea.
As a reference, last winter I bought a private sale 2002 Club Car DS (reconditioned in '08) in excellent condition for $2050. It has three year old batteries which will be likely replaced in the fall.
Good luck with your new cart, sad to lose a sparky to the dark side
