I know nothing about this Chevelle for sale,but I wish they wouldn't use interpolation estimates as reference.
To say that this LS5 Chevelle is one of 22 made,is not Factual.They do use a disclaimer in their ad,but all to often this figure will be repeated down the line,and thus become gospel.
To date no body,not even Chevrolet,knows for sure how many were built with those options.....Unless of course Jim Mattison can shine some light on this!
