I am not getting in a argument here,and i respect your opinion.(and I repeat i am not planning to sale the name) Anyway I disagree on your Z statement. Recently a namepros members has sold ATAZ in excess of 700$ at sedo.(I know is a VCVC) And there are surely more examples.
With this I am not saying your appraisal is wrong or right. Just stating that on your method, google' s returns are very important. And 2300 returns is obviously a poor performance. I own a single italian world 6 letters, widely used and dot com that means "take" , easy to spell with 957000 return s in google.
Not knowing the word, how much would you appraise it?
