Alex is the man to see he knows his vehicles. Easy to talk to great customer service, he finds the vehicle you need. Alex help us in every aspect. Would highly recommend this dealership and recommend you all to see Alex.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Happy to purchase from this dealership rather than others in town! Turned out to be much better deal and car. Thank you

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Thank you to the service team for your getting me all set for my roadtrip!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

This is the second car I've bought from CarMax (I also once sold a car). Every experience has been fantastic but this actually ranks as the best. Sales Consultant LaShinda John answered every question I had via email and then, for financing, by phone so that I walked in with the exact make, model and trim I wanted waiting for me to test drive and pre-approved for financing. The entire in-dealer experience took less than an hour and a half. Fantastic company and fantastic sales consultant.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Gave us even a better deal than expected. Highly recommend them. No high pressure and family friendly. Kids really liked the life size Marvel statues.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Joe Aksamitowski does an incredible job in all aspects of customer service from beginning to end for me and my family. In this case I needed a new transmission, a costly and lengthy process, and was allowed to have a loaner car free of charge for 7-8 days in December 2025. Joe kept me updated throughout the process. Despite the cost of almost $7K after allowable deductions, I was very satisfied with the outcome. He is tremendous with customer service. I have spent well over $400,000 at this dealership over the past 30 years through the 3-4 dealership changes on 8-9 new cars as well as R & M. What is consistent is great customer service. In addition, Roger Aguilera and Chris Capperelli are also great with customer service. Thank you. Lowell B. Raven, CPA

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

The dealership had a great selection of quality used cars, all well-maintained and reasonably priced. I appreciated their transparency and honesty throughout the process, including providing detailed vehicle history reports. The financing process was also seamless, offering several options and explaining everything clearly. I left feeling confident and satisfied with my purchase. Overall, I highly recommend Affinity Auto Sales to anyone looking for a reliable used car and a pleasant buying experience. Thank you to the entire team for making this such a positive experience!

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Mike Pendleton was great, even though I was looking for Calvin, nevertheless, either was great! Paul was awesome as well!! I would definitely recommend you guys to all of my friends!

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I come in to service all the time and Dennis and his team are great! Always providing me with great insights on my vehicle and I enjoy the videos of my vehicle as well! Highly recommend coming here for service and also sales! Can’t wait to upgrade into a new Mazda soon with this amazing and informative staff.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Chris does an outstanding job every time I visit. He is very accommodating and always aware of my needs and my time. Only place I service all my vehicles (3) and drive 30 minutes even though there are 2 Chevy dealers much closer.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Very professional and prompt service. I was very happy with the outstanding customer care I received and would highly recommend them.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Very professional, excellent communication Friendly staff, and had the vehicle we wanted, would deal with them again

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Second car I purchased from castle gmc our sales person was Nubia /great experience every time helpful and always greats us as family highly recommend castle gmc Nubia and Brandon will take very good care of you . 👍🏻
