Professional and helpful
Worked with Alan Karow. Extremely professional and helpful. Highly recommend him and Garber Bay Road. They have won all my future business. Please visit Alan.
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Jon Randall is solid.
Jon Randall is solid. He was very patient and knowledgeable. I received a very fair trade-in price and there were zero games, which made this the best car buying experience I’ve had thus far.
Great car for work!!
Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

The dealership was fantastic overall.
The dealership was fantastic overall. I worked with Charles Van Horn. He was great, very accommodating and laid back. Lane in finance was very difficult to work with, however. A simple task ended up taking several weeks, his communication and service was extremely poor. That is the only reason the review isn't 5 stars. I will probably go back for my next vehicle because of how great everything else was though.
Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Response to my inquiry was prompt and courteous.
Response to my inquiry was prompt and courteous. So was the follow-up as the sales agent checked with me regularly. The initial internet presentation of the car wasn't great as pictures were of "other" cars of the wrong color, etc. I didn't buy the car so I don't know what happened after a few days.
Really impressed with the performance
Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me

Great deal from Coulter
Coulter dealerships have been very good to me with the vehicles I have bought from them in the past. Coulter Cadillac was the best experience yet. I got a great deal and I know it! The deal was mostly done on line and did not change the day the xt6 was picked up. This is not the usual dealership experience. No wonder Coulter has been around for 100 years. Thank you very much, Steve and Nancy

I had an incredible experience at Tasca GMC in Palm
I had an incredible experience at Tasca GMC in Palm Harbor. From start to finish, the entire team made the process smooth and stress-free. A special shoutout to Lenny — he was absolutely amazing to work with. He was kind, patient, and really took the time to make sure everything went perfectly. It’s rare to come across someone who truly cares the way he does. I’m extremely grateful for the professionalism and customer service I received here, and I’m looking forward to working with Lenny and the team again in the future. Highly recommend!

Drew was there from our first call until we went home with a new Chevy. He worked hard to get us where we needed to be financially. Explained everything we needed to know about the vehicle we purchased. Drew was also there for some follow up calls, very patient and kind. We will definitely return for our next vehicle

I live in Utah but recently bought an Escalade from
I live in Utah but recently bought an Escalade from Halladay Cadillac in Cheyenne and honestly, I was just super impressed with everyone. You can tell these guys know how to treat people right and run a solid, honest dealership. They picked me up at the Denver airport and drove me up to Cheyenne. After the sale, on my way home I noticed that the USB and HDMI ports in the vehicle did not work. It was unexpected, but the way they handled it really meant a lot. The repair wasn't cheap but they didn’t make excuses, they just took care of it and made things right. That kind of service is rare, and it meant a lot. It was clear they stood behind what they sold, and that goes a long way. I’d absolutely buy from them again and recommend them to anyone who wants to work with good people who actually care about doing the right thing. Special thanks to Bryon the salesman who was super helpful and never pushy and John the sales manager who was a pleasure to work with in getting the issue resolved after the purchase and Shawn Smith the GM for standing behind the sale and being willing to take care of it. If I could give more than 5 stars I would.

First and foremost I want to thank Gregory Rodriguez, he made my purchasing experience like no other. From the test drive through negotiating a reasonable monthly payment, and finally closing the deal with my vehicle. Gregory was extremely courteous and professional. I usually purchase a new vehicle every 3 to 4 years and I have never dealt with a sales representative like Gregory Rodriguez, he is the reason I will purchase my next vehicle(s) at Capital1from here on. The financial agent Melanie Davis made the financial paperwork effortless, it was simple and she was very informative page per page. I reside in the Rio Grande Valley, and I will definitely make the drive again to purchase my next vehicle in the future. I will definitely recommend Capital 1 to my friends and relatives.
