I'm saying it would make no difference in a purchase. If I liked the guitar (and neck) otherwise, but wanted the string spacing at the nut to be a little wider, narrower, equal distance, equal centers, or whatever, I'd just change/alter the nut. OTOH, if a guitar has a 1 5/8" nut width and I prefer a 1 3/4" nut, then I'm not interested because I know the neck is not physically wide enough. Rejecting a guitar because the string spacing (not neck width) at the nut doesn't suit you is like rejecting a new car because the seat is not adjusted the way you like.
