The Opel Service Seretakis application is a pioneering application for the data of the country's garages. Replaces the classic vehicle maintenance book with an electronic one. Every work performed is registered either by us or the client. Note that the first registration is mandatory by our workshop. Notifications of scheduled future assignments are sent as well as notifications of possible offers for some periods. Supports more than one vehicle per user. It is a tool for organizing their vehicle maintenance file.
