Stellar Customer Service Always
Tony McIntosh is the most caring & knowledgeable car sales consultant we've done business with for over 15 years. He knows about future Honda vehicle trim updates and competitive models. He has always been very fair & honest upfront about everything when buying a car. I know if there is ever a problem with my car and it hasn't been dealt with appropriately (which is very rare) by another department, he will do everything he can to help make it right. Maroone Honda has made vast improvements since the transition from Front Range Honda to the current dealership. My only complaint is they seem overcrowded at times because of the increased number of additional Honda owners, so it can be difficult to find a place if you're waiting for services. Of course, I understand the supply issues and struggles that all dealerships are currently facing; however, they have always been quick to relay any delays or issues for inventory, parts, or services. Terri Jameson is an amazing Service Consultant. She and the entire service technician team are very knowledgeable and helpful whenever I have issues with any of my vehicles. I trust them completely.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Great and professional
John was great. He kept us informed. He took photos of what was wrong! He got our job done in good order. We were very impressed. We will not be taking our Jeep anywhere but to it’s home at Perkins.
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Amazing Services.
Both my husband and I have bought all our vehicles through them. No hassles, no stress, no sitting for hours. Always truthful. Will is so down to earth and so willing to work with you. They have integrity and are very accomodating. It's a pleasure. Will always buy through Hoo Motors.

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

Best truck ever!!!
I bought mine new in 2005. It now has 250,000 miles and still purring like a lion. It has been very well maintained has had very few repairs. It has been a pleasure to drive it’s both comfortable and has lots of power. I like how the front center compartment will go up for a sixth seat. It was able to hold the whole family with car seats and all in the back. It’s a good solid truck. It has never been garaged and it’s sat out in the Oregon coast rains now for seven years. It is finally showing signs of rust on the hood front edge and some color discoloration on the hood and roof. Its gone through a few head and tail light bulbs and had a few tire changes and brake pads jobs but what can you expect for a truck that is 18 years old with that many miles. I’ve been super pleased with it and when the sad day comes and it won’t run anymore, I might just buy another 2005 with less miles because it’s been so good.

It's All About Customer Service
The customer service at Carmax is excellent. This is by far the best car buying experience I've ever had. They were super friendly and did not waste a lot of my time. They were extremely efficient throughout the entire process.
My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Super easy transaction! Located the desired car online, called for appointment, took vehicle for a quick test drive and closed the deal. People were friendly, helpful and efficient! Would recommend!
I've had the truck a month, and so far so good!
It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

I recently purchased a car from Lakeside Auto Brokers, and the experience was nothing short of exceptional. My salesman, Ed, was truly outstanding—by far the best I've dealt with in my 55 years. Despite my recent Chapter 13 bankruptcy, Ed worked tirelessly to secure financing at a fair rate, and his dedication made all the difference. On top of that, the vehicle was priced very competitively. I wholeheartedly recommend Lakeside Auto Brokers 100%—if you want to be well taken care of, ask for Ed.

141,000 SLT Still Going Strong
SLT with most options. Purchased at 127k. Currently have 141k after 17 months of ownership. The tranny that came with it was not original. I have had to replace ball joints, a/c condenser, brakes, wheels, radiator, a battery and a starter. Can't complain at this mileage. This is one of the quietest vehicles I have owned (that includes Audi A8's) and it's shod with Cooper Discover AT3's that chomp through snow like my Toro snow thrower. I also replaced the stock halogen bulbs with LED's and what a difference! The interior is comfortable, and I did replace the drivers seat bottom cushion. The nav system sucks, it's not very intuitive and it isn't very good at mapping the best route. Besides, I use my sedan for long trips. Phone integration is a breeze. Radio surprisingly decent. Everything works as it should. It's easy to pop the kayaks in the bed and the ebikes on a carrier and head out for the weekend. When moving stuff, I have the 80" bed so I can fit loads of stuff under the hard tonneau cover. The interior still has NO squeaks or rattles. Amazing. The heated seats are slow to heat, and the heated wheel is slow to warm up. But this thing is such a beast in the snow and rain I don't want to drive anything else! All in all a very reliable, well-built, and for the genre a good-looking vehicle. People tell me all the time what a nice looking truck I have. It's stock. Thanks, GMC.

Very Good Truck
I bought my 4x4, 5.3L ext cab at 2 years old. The records show that it had some serious factory defects (transfer case, oil pump) before I got it. Its been a great truck for me as its never been in the shop for repair. The only work I've had to do to it has been oil & filter changes, new battery and new tires. I've put 100,000 miles on it and it has 141,000 on it now. I has a few nuisance failures like high beams won't come on (the lights have been bench tested to work) and the window/mirror switches on the driver's door are failing. mechanically though, its bullet-proof.

VIN Verification Recommended!
After moving to CO from out of state, I went by Springs Auto Group and Adam Alldredge helped me with a VIN verification. Easy, quick, and courteous! Would definitely recommend!
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.
