My advisor Adam was great and my oil change was fast.
My advisor Adam was great and my oil change was fast. I was updated during the process about suggestions for my car an I was able to accept them or deny them through a link with the text message they sent me.
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

5 stars
We arrived less than 60 mins before closing on a holiday. We were super impressed and we went home with a new car. It was after closing and more than one person was still there working. You don?t see that these days. Our car salesman even took a selfie with us.
2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

I took my little Buick Encore there because the check
I took my little Buick Encore there because the check engine light was on. My mechanics name was Nico. He was very informative and responsive. Let me know what was going on through the whole process. These people are great! Reasonably priced. I will absolutely go back there.
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.

I had a great experience buying my Audi here!
I had a great experience buying my Audi here! The entire process was smooth and stress-free from start to finish. The sales team was professional, friendly, and never pushy ? they listened to what I wanted and helped me find the perfect vehicle within my budget. The finance department made everything simple and clearly explained all the paperwork. The car was clean, well-prepped, and exactly as described when I arrived. I appreciated how transparent and efficient everyone was throughout the buying process. Highly recommend this dealership if you?re looking for an Audi!
Love my GMC HD
I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

This dealership was amazing and I highly recommend. When purchasing my new truck, they worked with me to find a price that worked for the both of us. Then when I was an idiot and did not see hail damage due to frost, they further helped by paying for half of the hail damage repair. 5 stars is too low. Eric was awesome and all the managers were amazing. Can’t speak highly enough.

Selling my Travel Trailer
I was referred to Dan by a friend of a friend. I didn't really even know who I was calling until I heard the last name - Berkenkotter. He was very kind and friendly and told me that he or his staff could bring my 2010 Heartland North Trail Travel Trailer in from the storage lot about 15 miles away and then they would make me an offer or they could put it on consignment for me. I took the offer, because I'd done my research and I knew it was a reasonable offer. Very nice staff, it's got the feel of an old time family business where deals are made with handshakes. Very happy!

Gregory at Castle Chevy GMC is the automotive wizard we
Gregory at Castle Chevy GMC is the automotive wizard we all need! When my wife’s 2023 GMC Yukon XL needed some TLC, Gregory didn’t just fix the issue—he played detective, keeping it an extra day to crack the case like a vehicular Sherlock. And as if that wasn’t enough, he sprinkled some magic dust on a couple of minor, non-essential fixes that were the cherry on top of this service sundae. Professional, communicative, and an absolute delight to work with, Gregory’s the guy who makes you wonder why all car repairs can’t be this fun. Highly recommend him and the Castle Chevy GMC crew for service that’s smoother than a Yukon on cruise control!

Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,
If owned Three Avalanche
It is a strong reliable truck and I would likae to have one for myself as a work truck and hauling heavy equipment like a man lift and compressor and still do some light duty work

An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

I was in the market for truck and messaged Ryan after finding a great deal off the Sterling Auto website. This was one of the easiest, stress free, no pressure experiences I’ve ever had purchasing a vehicle. I was in and out the door in under 2 hours. Highly recommend. Everyone I met with was kind and straight to the point. I highly recommend and would happily do business with them again.

Our experience with Jason Montgomery was absolutely fantastic! From the very beginning of our car search, Jason went above and beyond to help us find the perfect vehicle. He was incredibly patient, knowledgeable, and genuinely cared about making sure we found exactly what we wanted. When it came time to go over our new truck, Jason took the time to explain every feature in detail ? making sure we understood how everything worked and felt completely comfortable before we drove off the lot. His professionalism, friendliness, and thoroughness truly made the whole process easy and enjoyable. We couldn?t be happier with our new truck or the amazing service we received from Jason. If you?re looking for someone who truly goes the extra mile, Jason Montgomery is the person to see!

Was looking for a 2025 GMC Acadia Denali.
Was looking for a 2025 GMC Acadia Denali. Went to AutoNation and was met by Caden Noar. He was fantastic! Showed us the Acadia he had on the lot, gave us a test ride and answered all our questions. Not once, did he pressure us to buy but was more interested in answering our questions. After the test drive, we noticed a Buick Enclave Avenir in the lot as we were exiting the dealership. Liked the car looks and went back into the dealership to see if Caden was available to show us the car. We knew nothing about the car. He came out, gave us a test drive, answered our questions and then asked us if we would like to see another feature of the car, so out we went for another drive. Again, no pressure to buy and we parted. Over the weekend, we decided we really loved the car and called Caden on Monday to see if we could discuss the price and terms. Bottom line, we bought the car at the price we wanted. Outstanding service from Caden to the Sales Manager to the Contract/Finance Team!

Amazing service
About 3 weeks ago my husband and I were looking to buy a newer used vehicle. Kevin Calderón stepped up and managed to get us into a 2019 Mitsubishi Cross AWD. It was the best experience we've ever had. We were in and out of the dealership within an hour. I highly recommend Christopher Dodge and Kevin Calderón for your future vehicle needs! Thank you, Kevin!!
