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.

Ford Bronco Experience
Beyond impressed with the professionalism and knowledge of Fady and Antonio. I traveled from Tennessee just to order from this dealership because of these two employees. Not only did they take time to answer all my questions and share their own experience and knowledge of the Ford Bronco I was interested in, they did all this knowing I was just a curious out of state customer who more than likely would not be back. That first visit left such an impression that I did indeed come back! From the first visit just to see the Bronco in person, to placing my own Bronco order to completing the sale and pick up of my Bronco, these gentleman were top notch! If you want an exceptional car buying experience, I highly recommend Suburban Ford of Romeo, be sure to ask for Fady!
Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

The "Product Specialist" (AKA Sales person), Larry
The "Product Specialist" (AKA Sales person), Larry Hendrie was great! He carefully walked me through the process of what was needed to secure the Used vehicle I wanted to purchase that I found via the internet. I drove 200+ miles to get it! He was very accommodating assisting me with completing my navigation plans that allowed me to travel to NY to purchase the car. Larry was also very attentive sending me a reminder about our upcoming appointment and also called later in the day to be sure I made it home safely with no concerns about the vehicle. Great sales person. Thank you!!
Unbelievable towing capacity.
The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

I worked with Greg Pike who was very accommodating.
I worked with Greg Pike who was very accommodating. He was able to locate the vehicle that we wanted in a 2025 Encore GX quickly. There were no issues and the experience was very enjoyable.
Capable truck with the right options
Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

I’m in Georgia and did everything online.
I’m in Georgia and did everything online. I purchased a X4 M40i. The price was great and the car was the perfect fit for me. Marisela was wonderful to work with and did all I requested before finalizing my decision to buy. The longest process was the return paperwork being delivered by FedEx! Otherwise, it was a seamless process. I also want to thank Ahmed and George. I appreciate everyone involved for following up and making sure my car was delivered and if the car met my expectations. Thank you so much!

Drew Koba is the best Parts person you have
Drew Koba in the Parts Department is such an asset to the company. I have used him for years and would recommend him and this dealership to anyone. He is personable and extremely professional. It is almost as though you think you are talking to your long-lost friend. As a business, he is the type of employee you want. He keeps me, and I am sure others, coming back again and again.

My wife and I came in to look at two vehicles.
My wife and I came in to look at two vehicles. We were surprised that the General Manager was the one to greet us while I was looking under the first vehicle. Steve was very polite and introduced himself and asked what they could do to help. We had a short conversation and then he grabbed a sales associate, Nick, and both were very accommodating and patient with our inquiries about the used vehicles. They provided hard copies of everything from the Carfax to their own vehicle inspection report for us to review. They were also accommodating while we left to discuss and then came back to have an offsite third-party pre-purchase inspection done on one of the vehicles. We came back with no real issues and closed the sale. We were even the last ones out the door a few minutes after hours. Both Steve and Nick were both there to see us off in our new, to us at least, vehicle. Would defiantly not hesitate to look at Walser again as the service earned my repeat business.

I like everything about the dealership, from the vehicle
I like everything about the dealership, from the vehicle selection to the sales representatives. However, I have a couple of issues: I referred my son to the dealership, he bought a car, and I was told I would receive a $100 referral. It’s been a few months, and I still haven’t received it. Additionally, the coupon book for my son’s vehicle purchase hasn’t arrived yet; he keeps being told it was mailed out. Other than that, I love the dealership!
