Great personal service

Friendly efficiency and local experience

Always a good experience having my truck serviced!! Everyone is always smiling and know your name!! I could have my truck serviced where I live but I trust the people at Spearfish cause I know they will take care me!!

Best dealership in the State of South Dakota!

got right in for oil change. no hassel

Our first time having service at this Spearfish Dealership. Wonderful service!!! Guys at the counter for service were very good at their job.

Took great care of me as always

John and Troy are always great to work with in the service department! Always friendly, helpful and staff is timely! I will be a customer at Spearfish Motors for years to come!!

The maintenance department always answers questions and gives quality service.

We have used Spearfish GMC for our last 2 purchases. We have always had wonderful service there. Rocky has been our Sales guy both times and we appreciate his laid back no pressure approach. John in service has always been so wonderful as well. When we have called with questions on our previous car he has always been very accommodating and willing to get us in if needed. I appreciate the “small” town feel when working with Spearfish GMC and we will continue to support them and purchase cars there in the future.

Always professional

Everything requested was addressed quickly and thoroughly.

Always a great experience! They value your business and take good care of your vehicle always on top with the inspection. Bonus is the wash after service! I have referred 3 friends/neighbors who feel the same!

Jason and Rocky were very knowledgeable, helpful and kind making our purchasing experience very pleasant.

Everyone at your organization makes me feel like family. Awesome.

We got in on time and excellent service and answered all our questions.

Your service team was great on answering the questions that I had in regard to the winter needs of my new 2025 GMC truck. I would recommend your service team to anyone looking for outstanding service. They were great on getting what I needed done and in a reasonable time.

Our 2nd free oil change nice to have free ones Easy to schedule gave us a loaner pu Good service & employees

This is the best service department for any dealership I’ve been to. John and Troy take care of any issue you have at every opportunity. Very well done, thank you!

Whether we are buying a car or servicing a car we always have excellent service. The service department goes over and above and we drive 60 miles one way to take our vehicles to them.

Jason is very responsive, competent and shows integrity.

Great team very friendly and polite.

We appreciate that the mechanics have worked through the many issues that the GMC Acadia had when we purchased it used with issues. So far it is driving great now.

The best service department

Steve Horner and the staff at Spearfish GMC Cadillac were very professional, knowledgeable and courteous throughout our vehicle buying experience.

Great service

Jason Konstant is an excellent salesman with great instincts. He remembered what we liked and as a result provided the perfect vehicle. It was a very pleasant, no pressure situation (which we really appreciated). I highly recommend him & Spearfish Motors.

Very courteous, attentive to our needs, and very professional.

Shocked at the cost of service. Because of the problems with the 6.2 engine the service cost nearly doubled. I can’t blame the dealership for this. I feel that General Motors should cover the difference.

On time, personnel and experts

The service is second to none! Very friendly.

The guys did a great job and quick !

Very good experience. Thanks

Always great service from this department.

Was greeted when I arrived, serviced my car in a timely manner, and handed me my key and said good bye (after I paid my bill).

Everything went well I was in and out and everyone was great.

John took care of and explained everything

Very accommodating and efficient!

John was great at working with my schedule and helping with the warranty

I was in and out in a timely manner!

Always friendly and helpful. I appreciate the service I receive.

We just had an oil change and service job on my GMC Terrain. We also purchased new tires. Spearfish Motors always does a wonderful job…we totally trust them. They always work with us to get an appointment at a time convenient for us to travel the 150 miles to get there. We appreciate them!

Have always had a positive experience here in the many cars we've purchased.

Everyone from the service desk (John & Troy) to the service tech(Terry) & sales were very helpful and professional. I would recommend Spearfish GMC to anyone!

I get excellent service every time I go in. I am greeted at the door and every action is treated professionally.

Service department is #1 in customer service & car for my truck! These mechanics are the best!

Always willing to help!

.

It was set up for a service and hook up to a computer to fix our problem! Instead the service manager told me how to fix the problem which I’ve tried doing several time! We still have the problems and don’t know how or where to get it fixed!

It was fine. No issues at all.

They got me right in and back on the road in 1 hour

Appreciate the prompt service, it really helped me as I am in college in Gillette and it would have been hard to have no vehicle. I dropped it off in the morning and it was repaired the same day. Thanks.

Very friendly, prompt service

Excellent treatment for my truck and and for me!

Atmosphere was very comfortable and the machanic working on our vehicle was very proficient and informative. He did a very thorough job and eficient job fixing the issues with the vehicle. We will definitely be using him in the future for maintemance on our vehicles.
