Originally $300 from Helm.
These contain 4000 pages and weigh nearly 12 pounds! They have been used, but gently by home mechanic. Binding is good, all pages are present...but there are some grease spots, finger prints, bent pages etc.
So if you're looking for new, spring for the $300.
If used but loved works for you, The first $150 +$7.50 postage (media mail) gets this set.
As a side note, there were so few changes in HHR's over the years that this set ought to applicable to almost all years with very few exceptions.
