Fleet services

Here at Diamond State Automotive, we pride ourselves in providing excellent service in the following areas:

We follow all manufacturer guidelines of service for company fleet vehicles.

  • Every preventative maintenance service comes with vehicle pick-up/drop-off and a full vehicle courtesy inspection
  • Courtesy inspections, tire rotations and tire repairs are complimentary.
  • Our systems build a database of your vehicles and tracks average daily mileage based on services. Our system automatically generates an appointment for next required service at the time of previous service. This allows us to send out reminder emails and/or text messages to clients informing them their vehicle is due for service again. That email/text allows the client to respond directly and either confirm or reschedule. Our fleet tracking is built to take the whole process out of your hands and lets us effectively manage it. In turn, it frees up your time and brings long term maintenance costs down across the board.
  • You will receive a loyalty website where you can log in and track all your vehicle records from our services and any notations made about those vehicles.
  • You can request appointments via phone or through our website
  • Accounts are set up on a Net 30 basis.
  • We do not require service contracts. We believe our work and the benefits of our company should make the client want to use us as opposed to being bound by a contract.

Give us a call at (302) 764-7294 to schedule an auto repair appointment at our Edgemoor Road facility in Claymont or call (302) 325-2002 for information on our fleet services at our Airport Road facility in New Castle.
