S - Service book
Service book/cost/history - To ensure safety and reliability, cars should be serviced as directed in the manufacturer's handbook. See whatcar.com's running costs section in a car review for the maximum servicing cost for every model.
A dealer stamp should be entered into the car's service book to show the necessary checks and work have been done. Failure to service a car and maintain its service history can have a negative impact on its used value. (See Full service history).
