I bought the CD Rom and have used it for my 560SEL. Compare the price of the manual to the hourly labor cost to get your car worked on. This manual is specific to your car, and provided by the manufacturer. It has more information in it than you will ever need. Buy the CD Rom and use it for a few repairs. It will pay for itself, many times over.
