What to price a 1970 Super Bird at my friend is getting in a multi car trade

I wouldn't pay $10,000 for a paint job now, not sure how it sounds like a cheap job 12 years ago lol.
talking about a correct resto paint job by a shop that does collector cars and knows mopars. This means a rotisserie, windows removed, doors off, weather striping removed, correct wheel well treatment, engine bay painted, and all the little stuff this superbird has like nose cone details, prep for the vinyl top, seam sealer, decals applied, etc etc.. The. Windows installed, panels and Doors installed and aligned. Ya you could paint a superbird for 10'grand back then but I don't think it would be a show stopper.
