The service advisor kept me informed of as they diagnosed the problem, determined what parts needed to be replaced, and provided an estimated final cost. The service appears to have corrected the problem with my AC, but I was disappointed that for $4k the service tech(s) didn't bother to clean the greasy hand prints off the hood and fenders.

Long wait to work with finance department. HUD didn’t work when we drove off the lot and the salesman knew about it. The salesperson was very immature and used some unprofessional language in his text back and forth. I had to talk tell i was blue in the face to come to a resolution for the hud repair.

Soon after I took delivery of my 2025 Sierra Denali the radio quit working. Thinking it was something I had done I went to the dealer and discussed the matter with the salesman who sold me the truck. He tried to rectify the situation but could not. I then went to the service department and talked with Robert, who is the service manager I normally deal with. The earliest service appointment available was almost two weeks away. I explained to Robert I was leaving on a trip in a few days and would like to have the radio working. Robert was able to fit me in two days latter and after a service technician and GM trouble shot the system it turned out to be a long standing problem GM has been unable to solve. The radio still comes and goes but I feel the dealer deserves a great deal of credit for squeezing me in and really trying to resolve the issue. This is the prime reason I continue to do business with Twin City Buick. They have consistently made me feel appreciated and have always gone the extra mile to take care of me.

I arrived a few minutes early for my appointment. There was not room to pull inside. I expected things to move fairly soon, so waited outside until it became clear that space would not be available soon. The technician wasn't friendly, but arranged for the work to be done on my vehicle. I went to the waiting room. I never heard from anyone while I waited. After more time than I thought it should take, I went back to the service area. My vehicle was outside, and appeared to be ready to go. I didn't see the technician who signed me in. The other technician said that he had gone to lunch, but had left my tag on the desk for someone else to handle. I was never contacted in the waiting room about how the work was progressing or if additional services were recommended. The (other) technician who completed my paperwork gave me a discount on the price of the oil change for the additional waiting time. My vehicle took twice as much DEF on this visit as it had previously, which seems odd. It's convenient to have DEF filled at the same time, but I will do it myself in the future. Overall, it was not a good experience.

The simple words as they handed me the keys of “enjoy your vacation” meant a lot. I will repay this gesture by buying a vehicle from them again & using their service dept. Thank you!

Time was the issue. A routine oil change/tire rotation took over 2 hours. Waited over 15 minutes to just get checked in then over an hour for the work. I had an appointment and arrived on time. I understand that this service may not be a priority given the profit on it, but if you are going to offer it, the do it right. The cost is about the same or maybe a little higher than the instant oil change places, there is no reason drive the extra distance and take all the extra time to come there for this type of service.

Solid one-star for the service I received. I paid the premium dealership price for taking my car here and got gas station quality service. $800 in labor and the tech cracked my plenum cover and said nothing about it. Not to mention, when they called to quote me a price, he left a voicemail and then went to lunch. I called back no more than five minutes later and ended up having to call a different line to get someone on the phone to approve the work. Overall, just not the kind of service I expect when I'm being charged $150/hr in labor from a 'Certified' Dealership.

Maintaining my truck at Twin City GMC is a snap. Show up at the appointed time, spend some time in the lounge, and then the serviced manager comes and explains what was serviced and gives me an overview of the condition of the vehicle. Same dependable done right the first time service as I have come to expect. Life is good.

On or about the time I was told my car would be finish I am notified that my car is ready, I am directed to the cashier and greeted with a friendly smile and I complete my payment. I get in my car and check if the air pressure of the tires have been equalized and that the oil percentage has been reset to 100%. It has been another pleasant visit to Twin City Buick.

We had the BEST experience we’ve ever had buying a new car this past weekend at your dealership. We traded in our 6th Tahoe for a Yukon. In the past we haven’t always felt comfortable with sales people at other dealerships. Saturday we had the pleasure of working with Jennie Bacon. She was professional and fun and didn’t pressure us into something we didn’t want. She worked very hard to get us to an agreeable purchase amount and did everything in her will power to get our business and make us happy with the purchase. I have already name dropped to a few family and friends to look her up if they need a vehicle. Everyone we came in contact with was just awesome there!!

If I searched the world over, I feel certain that I could not find a better service department than at Twin City Buick GMC! Guys that really care about the work they do and the service they provide. Guys that take the time to talk it out with the customer and formulate a plan for what needs to be done to the vehicle. Guys that really know the customer's vehicle, that remember the vehicle and recall what they did last time it was in for service. David is one of those that strives to make the customer's experience as positive as it can be. Anticipating his customer's needs and making certain the customer is pleased when he drives away. These guys, and especially David, are the best - countrywide. They just have to be, I know it.
