I agree with Ray.
I have the Clymer and later bought the factory manual, BIG, BIG DIFFERENCE!!!!!
With the OEM book, the pictures are much better and the values for tests and trouble shooting are right there with the pics and or instructions. My book cost $50 with free shipping and was here in 2-3 days. The cover page looks like a copy, but the rest of the pages look great. Clear sharp pictures, no smudges. The chapters are set up a bit differently than the Clymer manual, but I am adjusting to that. So I will keep both and rely on the OEM. IN addition there is information and pictures in the OEM book that are not in the Clymer.
I really, really like the OEM book.
