Same as mine, bought it new and still have it with 130K on the clock. Great car and I can understand that you would want to keep it but according to the market, worth nothing. Repairing could be very expensive unless you can pick up the parts from a wrecker or a cheap complete doner car. If you are flush enough to write off the cost of repair then by all means, otherwise you might want to look at other options.
