Abstract This volume describes the development of the life cycle maintenance costs for 212 sales—leading 1970 through 1975 passenger cars and light trucks. These costs pro- vide a data base for the Department of Transportation^ which describes the costs for parts and labor for performing both the scheduled (manufacturers recommended) and typical unscheduled (replacement of worn out parts) maintenance for each of these 212 vehicles. The actual data base is contained in Appendices E and F which are bound separately in Volumes II and III. This report also describes where the service work is performed during the vehicle life cycle. In addition, the automotive service industry has been characterized. This character- ization includes the facility (building) costs, land requirements, tools and equip- ment requirements, inventories investment costs and operating capital required to operate a service establishment. The major types of service facilities which perforir most of the commercially done repair work were characterized. These establishments are representative of the 29,600 new car dealers, 86,200 gasoline service stations, 30,650 independent repair garages, and 12,280 specialty shops in existence in 1975. The policies used by the service industry in pricing replacement parts are also presented. The report details the price discounting policies of the industry parts suppliers, including the automobile manufacturers and aftermarket parts manufac- turers, as well as those of the parts distribution system (jobbers, new car dealers, oil companies, and specialty shops). 17.

( "k;!*'' PREFACE This development and analysis of the Repair and Service Maintenance Data Base was performed for the U.S. Department of Transportation, Transportation Systems Center by the Automotive Technology Group at Arthur D. Little, Inc., under Contract Number DOT-TSC-1047 . The work was done under the guidance of Mr. Sanuel F. Powel, Ms. J. H. DeBlois, and Mr. James Kakatsakis, Technical Monitors at DOT/TSC. The Program Manager was Mr. Donald A. Hurter, assisted by Mrs. Nancy Gardella and Mr. Philip G. Gott. We would like to thank the Chilton Publishing Company, and in parti- cular, Mr. James Milne, as well as many others in the automotive industry for their contribution to the development of the vehicle maintenance data base. This is a three-volume report - Volume I presents a data base of the automobile and light truck service and repair industry and the current maintenance requirements of 212 domestic and foreign cars and light trucks through the years 1970-1975. Volume II includes the total cost summaries of Scheduled and Unscheduled Maintenance and Appendix E, Scheduled Maintenance Data Sheets. Volume III includes Appendix F, Unscheduled Maintenance Data Sheets. i i i ! S S e l I ~5 Vj 3 C 3 \ = a » a « ^ Itl i III!!
