My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

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.

pretty good service. always courteous and consistent.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Nothing much to say just talk to Sam.Very Profesional sales person highly recommend him, he didn't push me to run through hoops just showed results am greatful thank u Sam

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Very nice dealership experience. Jorge was very helpful and knowledgeable during my vehicle purchase. If you plan on purchasing from Toyota of Naperville, Jorge is the salesman to see.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

They made me feel welcome right away. Everyone was clearly dedicated to their role, and everything was well organised. I received excellent service with no high-pressure sales tactics. Thank you.

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

Service Department is top notch. Techs do great work. Happy to have them around. Keep up the good work!

Excellent service and knowledgeable. They Found me the best Subaru for my needs and preferences. Listened to all my questions and Concerns. Extra care all around from sales rep. Greg, manager Noah and finance George. I will look forward to maintaining my Outback purchase with Castle Autoplex in McHenry, IL.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Bought my first car here! Great deal! Nice people! 5 Stars service! They make me feel like family!

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!

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.

Extremely professional and sleek process working with this dealership. You can tell they carefully pick employees that represent and uphold knowledge and professionalism. Was a very non stressful process and will definitely buy my next car here.

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

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 . 👍🏻

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!

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.

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.

Great service and people fast and easy buying process will recommend to other family and friends fun environment and provide coffee and water will be back for all my service needs and repairs

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Roger was great and helped us find the perfect car! He is very knowledgeable and friendly. They had a great selection of cars for us.

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.

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.

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.

Kamal was very friendly, helpful, and knowledgeable. He made the car buying process the best we’ve ever experienced. We appreciated how patient he was while we decided which vehicle was the best for us. We are very happy with our choice and the dealership is top notch!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.
