Should I spring for a 1965 Valiant Signet Convertible?

4 years ago I bought my 65 Dart GT 273 convertible in running driving condition. Original paint, no rust. The interior wasn't as nice looking as yours. I paid $4200. I think I got a better than average deal looking around now. Hope this helps.
Even though I paid so little for it I now have $25k into it. I know I'm upside down but I didn't buy it as an investment anyway.
