Great Experience
by Kyle D from Windsor Colorado
September 24, 2018
We’ve never purchased any Chevy products before but this dealer changed our minds. The entire experience was great. Anne Richardson was very helpful and certainly not your “typical “ car salesperson. No pressure, simply gave us information but didn’t push. Financially, the cost and terms were surprisingly reasonable. Great experience!
Love the truck. Unhappy with the manufacturer
by Nick from Marysville , Ohio
March 25, 2018
I bought the diesel brand new. I could smell antifreeze in the front after a week. The dealership could not find a problem. After 32000 miles I had a low coolant alarm. After 4 days and some help from the internet the dealer found the leak at the bottom of the radiator. GM was generous enough to pay about $300 of a $750 bill for a problem that was there from the start. They gave me the illusion they cared and was going to give me more assistance. Nope! GM vehicles have a problem with the radiators and the connections. I have read many strings at the truck forums regarding coolant issues. The radiator has no cap which causes it to be very hard to "burp" the system when one needs to change out a poorly engineered radiator. The last GM vehicle for me.

This family run business is great. Scott found the used car I wanted and I love it! He even found a newer model than what I was initially looking at. Always professional service and overall fun to deal with. I will be returning for my service needs.

i do not know or care to learn about cars. Therefore, I go to McCaddons. Jon Berry has been pro-active in caring for my car, with full knowledge that I do not know abut cars. He makes recommendations in a language I can understand and then does the needed work. Better yet he does not recommend unneeded work. I will continue to trust the personnel and service.
Man, what a truck!
by Ed from DFW Area, Texas
January 2, 2019
I went from 2002 Chevy Avalanche (great truck) to my 2018 GMC Sierra Denali HD (2500 HD) Duramax. What a significant upgrade from 02. Only 3,500 miles so far, but xxxx, do I like my new truck. Best mileage on highway so far is 25.8 mpg with average hw mileage of around 20 mpg. The interior is simply superb, loaded with features, everything logically laid out, and super quiet (engine and road noise barely noticeable). Sound system and navigation (Bose Infortainment) are excellent. The ride is definitely stiffer, but not bad at all. But remember, this bad-boy is designed to haul a lot of weight. There are a lot of smart storage compartments throughout (not gimmicky or cheap) but the space under the rear-seats is very good (I added a cocoa storage organizer bin). So far I am loving my new truck. Denali plus offload options gave me all the luxury features I could ever ask for, as well as the sunroof, auto rear window, and factory bed liner. It was most expensive in its line, but I always keep my cars for 15+ years, so why not (I saved up for it).

Purchasing a used car

Max was very helpful during our car buying experience. He went to great lengths to make sure all our concerns were addressed. Khalid was super pleasant and made the financing process as enjoyable as financing can be. He is very personable and engaging. Lindsey was quick to respond to my internet inquiry. Two thumbs up to everyone who helped us purchase our car!!
Worst costumer support
by Dctt101 from Plain City, Ohio
January 8, 2019
This is a nice truck except for a few problems 1. The paint is cheap and scratches fairly easily for the price of the truck. 2. No rear heat or a/c in crew cab 3. The worst costumer service ever. (Let me explain) I took my truck to two different dealerships for the same problem multiple times for the drivers assist warning. They replaced the sensors under the seat at least twice and now saying they need to be replaced again @ $658. I keep asking why the problem is always intermittent with no answer. I suggested they check for a short, but was looked at like I was stupid I am over my warranty by a little over 600 miles and GM says they won't help me. You be the judges

2007 Ford Edge
by April from Loveland
November 24, 2018
I was searching for a replacement vehicle and had a used one in mind. I wanted something similar in size and performance to the one being replaced. I found this Ford on the website and decided it was worth a look. The process - from start to finish - took less time than I thought and that's always a good thing.
Buy the diesel version if you can afford it
August 9, 2018
Everything is great as far as comfort, style and reliability. However with any gas heavy duty there’s just no power and the mpg isn’t to brag about.

Great Overall Experience
by Chris from Denver, CO
November 28, 2018
After driving my car that I got when I was 16 for the past 13 years, I was a little rusty on the car buying experience. With friendly salesmen who weren’t pushy, I was able to make a deal in a relatively short period of time and felt great about my experience.
fowl like a locomotive
by retired & camping from Jacksonville, FL
August 12, 2014
We use our GMC Denali 2500 mostly for towing our 7,500 pound travel trailer. A big factor in high ratings is the diesel. With the tow/haul mode engaged, the mountains of north Georgia and the Smokies were no problem. Especially liked the exhaust brake on the long, steep downhills; it kept the rig totally safe under all braking conditions. We tow at 60 and get about 14 mpg with no headwind. If you tow campers or fifth wheelers, you know how good this is. We don't have the navigation screen, so the rear view camera appears on part of the rear view mirror. The image is small for hitching up; still need a spotter. The 2014 may not be as quiet as the upgraded 2015's, but noise is never an issue, and the Bose system sounds terrific. Just be really careful parking a crew cab with standard bed at Walmart......

The Perfect Truck
by NQSSea from Flemington, NJ
October 26, 2018
I might be biased because this is my dream truck but it's the coolest thing ever! I own a 2016 GMC Sierra SLE 2500hd and it is the bee's knee's for towing! It coming all set up for towing and it rides so smoothly! This truck effortlessly tows around my 2 - horse trailer with my two Irish Draughts in it, one of them being 17+ hands! All in all I LOVE this Truck! Thank you JJ Suk from Keller Bros for selling me this dream!

Sweet White Sierra XLT
by L:andmark Subaru from DealerRater.com
November 30, 2018
I found myself in need of a vehicle and looked at different options. I finally settled on a 2018 Sierra. I went to Weld County Garage because I serviced my other vehicle there and was impressed with the quality of service and the friendly atmosphere. Perry Cogburn showed me a number of vehicles and we worked a deal on the one I purchased. The process was very easy with no pressure. I highly recommend Weld County Garage and I'll continue shopping there.

Time and Effort
by Kim from DealerRater.com
November 29, 2018
I have been doing a lot of car sharing and needed a vehicle of my own to drive. I took a considerable amount of time making my decision and Kent Aenchbacher was ever patient and answered all my questions, working several estimates in finding the best vehicle for me. He made sure that I was confident and comfortable in my decision as I drove away in my 2019 GMC Terrain. I am a stickler when it comes to excellent customer service, having over 25 years of experience, and feel that this was provided to me. I would definitely purchase from Kent again. Thank you again for all your time and effort.
Best vehicle I've ever owned. This is my 1st diese
by Metalman from Spring,Tx
November 19, 2018
This truck has surprised me. Milage is unbelievable. I'm getting 23 mpg dry. I bought it to pull my travel trailer. My old truck went into passing gear going uphill. My new diesel stay at 1500 rpm uphill or down hill never misses a beat. I am impressed. It is a beast. I highly recommend the GMC 2500 HD.

Great Experience
by tami1213 from DealerRater.com
November 24, 2018
There was originally some miscommunication with the scheduling department. After we arrived at the dealership though, Ricky took ownership of our experience and did everything to make it more enjoyable. We had to come back to the dealership a few days later and the overall experience was great. We purchased a used car and were in and out in less than an hour. Ricky gave us some Starbucks gift cards to apologize for the original scheduling. He was not high pressure and we'd use him again!
Nicest truck I’ve ever owned
by Yaboi from Ogden, UT
January 7, 2019
Got the Duramax Sierra SLT crew cab with pretty much all the options, I’ve tried other trucks and currently have a 2007 Chevy Duramax and it turned me to GM from the ford and dodge diesels I’ve driven/owned in the past. Blows my mind with all the options, super comfortable and rides quite nice for a truck.
