Easy phone call scheduling, being a new customer got me in the system right away, and got a good idea of a quote before getting the car brought in. Got everything diagnosed, a good call to get approval to continue with the repair, and parts ordered/ installed in the same day. Definitely will utilize Great Lakes Service... read full comment

Bought a Ram Promaster cargo van from the establishment. Great service. When I got the vehicle back home there was an issue with the sliding door. They didn't hesitate to work with me in making it right. Would purchase another vehicle from this lot!

Had the check engine light on. They were honest and fair. They didn’t charge for stuff I didn’t need. Thanks to Nick and Randy for their help.
