Maryland Commercial Law Section 14-1002

      (a)      (1)      Before beginning any repair work on a motor vehicle for which a customer is charged more than $50, an automotive repair facility shall give the customer on his request a written statement which contains:

                  (i)      The estimated completion date; and

                  (ii)      The estimated price for labor and parts necessary to complete the work; and

                  (iii)      The estimated surcharge, if any.

            (2)      If the fee is disclosed to the customer before the estimate is made, the automotive repair facility may charge a reasonable fee for making the estimate.

      (b)      An automotive repair facility may not charge a customer without his consent any amount which exceeds the written estimate by 10 percent.

      (c)      An automotive repair facility is not liable for breach of the written estimated completion date for a repair if the delay is caused by:

            (1)      An act of God;

            (2)      Strike;

            (3)      Unexpected illness; or

            (4)      Unexpected shortage of labor or parts.

      (d)      This section does not require an automotive repair facility to give a written estimate if the facility does not agree to perform the requested repair work.
