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 and tire repairs are complimentary.
  • Our state of the art systems build client specific databases teaching age of vehicle and average daily mileage providing the customer direct communication automatically. Reducing the need of in-house vehicle maintenance tracking through automated service reminders. Simple one click confirmation/rescheduling with the flexibility to contact either the fleet manager or the specific driver.
  • 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
  • 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) 325-2002 for information on our fleet services at our Airport Road facility in New Castle.
