Where are the best places toget them?
Price around the internet as suggested and within a short period of time you will find out what is the retail price, and what the bargain prices are. And as suggested sometimes you find someone advertising a used one for a good price. I personally have both the AIM in copy and on a disc. My copy is from the early 80's so its pretty good and believe some of the newer versions do have much clearer pictures but it is something to watch out for as some are not too good. The Chassis Service and Overhaul Manuals do not have the issues like some of the AIM manuals have. Happy hunting!
