1970 Dart GT Value?

I hope this is the right area in the forum for this...
I bought a 1970 Dart GT from the original owner several months ago - has the original window sticker. I've tried my hardest to determine a value for it and cannot find any good past sales to compare against.
Any help or any ballpark values?

Window Sticker:
- Dodge Dart Custom (318 replaced in 1971 w/ 340)
- Vinyl Bucket Seats
- GT Package
- Console
- Torqueflite Trans (Not sure if that was replaced - has a 4 speed auto now)
- A/C
- Power Steering
- Vinyl Roof
