I'll agree with the $16-$20k mark. It's a good looking car, but I don't see him getting anything near $27k.
A perfectly restored, high optioned, '71 340 4 speed Demon is usually the $30-$35k range. I've only seen a few actually go for that much. And I mean
perfect. I have seen some
really nice Demon's sold around $20k. Heck I've seen some pretty nice one's in the $12-$15k range.
As far as the pistol grip goes, they never came with one but you can add them, a 71-74 B-body non-console shifter works pretty well. That's what I run in my '74 Duster/'71 Demon clone
