I'm in much the same situation, though I have several old cars & trucks. I am clearing them out, but pay enough in shop rent/etc., to make it a wise decision. If there is anyway you can hang on to it, the pay-off in a few years will be significant. In other words, if I owned your car, they'd have to pry the steering wheel
from my cold, dead hands! If she's suitable material, however, Barrett Jackson's would be your best bet for the "big" money. Best of luck with that decision!
