In the past when I was in my 20's, I used a Haynes manual for all the repairs I needed to make on a Chevy Bellair and, it was essential. Now I am in my senior years and, It still is a mainstay to understanding the problems I have with my car which is 27 years old. I'm not mechanically inclined but, it helps to have the manual to understand if there is something that needs to be fixed and, how much the part will cost and how much labor will be needed to fix my car.
