After reading this whole thread I can't believe you can let her go! I love my gold Dart Swinger (she's a '72 Y8 not Y4) and can't imagine letting a stranger have her.
There's only 13 hours left on the auction and the bidding isn't near the reserve so maybe you'll end up keeping the Dart until next Spring when the car shows start again.
I really want to wish you luck but boy, is it HARD! Okay, good luck. :(
