I called the dealership and advised them that OnStar sent me an e-mail that my 2015 Chevrolet Malibu was ready for an oil change. John told me to come in. I chose the key drop off method, parked the car and went to work. I then got a call from Ariel confirming the request for an oil change and for tire change from winter to spring. Before lunch I received another call from Ariel letting me know my vehicle was ready for pickup. Thanks for great service!
