I bought somewhere around 60 manuals from all different years from a closed dealership. $10 each + $5 shipping for CSMs. Electrical and New Product books are $5 +$5.
They are not perfect. I cleaned the dust from the covers the best i could. Some still have stains or bent edges. Do not buy one if you want a perfect one. The insides all seem just fine, they have been sitting in a garage for a long time and they are just mostly dusty and a little musty smelling.
The price is for shipping USPS medial mail to lower 48. PM if you need overseas shipment. Please only PM if you want to send a payment. PM me your paypal email address. Of course i take cash or money order.
