The Complete History of the Presidential State Car

Secret Service Provides Maintenance

All maintenance for the presidential state car is completed by the Secret Service as a security measure. This likely serves multiple purposes. By only having trusted Secret Service members complete vehicle maintenance, there is no risk of a person with malicious intent causing intentional damage to the vehicle or putting the Chief of State and his staff at risk. Additionally, keeping maintenance within the Secret Service limits the number of people who are able to view the vehicle. Given the high level of security associated with the state cars, and their complete destruction upon retirement, it is clear that officials do not want it inspected by outsiders.
