Stephanie - I reviewed your pictures here and on eBay. I think Ivy has potential, but she has a long way to go. In general, there are a lot of nice things about your car, with the exception of the seat tears, the interior is very nice. It does need lots of body/prep work, especially on the roof and front lip and a decent respray to make it more presentable. Tack on new seals for the glass and probably door seals, better bumpers and "misc." and this is a real project. It would be very easy to put $7,500 to $10,000 in your car and it might be a $7,500 to $10,000 when finished. Some will disagree but the automatic trans does not help the value, but it does make it slightly easier for a 5 speed swap. I'm afraid you need to either punt and walk away at a large loss now or make a commitment to a partial restoration. I could be very wrong, but if you get an offer near your starting ebay price, I'd take it (if you REALLY need to sell)
If it were my car and I enjoyed it--I would keep it, locate better bumpers, strip the exterior, sand and sand like there is no tomorrow and then take it to a quickie paint job place (Maaco) and have them patch the nose and throw on a coat of green. Once you sort out the seat cushions and trunk items, and re-install all the brightwork and glass, you'd be left with a fun driver and not need to worry about total perfection. I think you could make it a more presentable daily driver for ~$2K.
Hope this info helps and good luck with whatever your decision becomes.
