Jeff N was extremely helpful and efficient, getting us the exact vehicle we wanted from a different city. He did all of our financing over the phone and email so we didn't have to sit in the dealership for hours. Very nice experience!

I had a positive experience at the dealership. Jeff was a great sales man who listed to my concerns and ultimately was able to negotiate a great price for me on my new vehicle. He very quickly matched my pace throughout the sales process. Finance team was also great - they did not try to upsell me on other items that were not already part of the negotiated deal as it came time to do paperwork.

Harley my service rep was spot on the entire time and Mike L. followed up with me after hours outside of the dealership when I saw him. Not sure of the lady’s name I first talked to to tell of my issue and her scheduling my appointment was great. Thanks to all!! John Cozad

We purchased a truck from Billion in 2021. On 5/10/2025 we sent a text message to the salesperson from our purchase in 2021. He was working and met us at the door when we arrived (Jesse McGraw). We told Jesse what we were looking for in a truck. His awareness of what was available allowed him to waste no time and within 5 minutes we were looking at choices from 4 trucks. Jesse was very easy to communicate with, no pressure, answered all our questions. Jesse was the reason we came back to Billion. Derek in finance made the financial aspect to the transaction very easy. Derek got us the best financing option. It was truly a very pleasant and uncomplicated transaction thanks to these two great individuals!!!

Travis helped us. We brought in our 2018 enclave that had a bulletin out to fix a problem with the fuel injector part of the engine. Was told a diagnostic would only take 2-3 hours. I messaged him and had to call. Hard to reach. When I did finally get through to him 4 hours after I dropped it, he told me that everyone was headed to lunch and could get it buttoned up when the mechanic returned if I did not want them to go any further. Multiple times, service was poor and felt dismissed. Ended up having my husband take over as my afternoon was busy. My husband also commented on feeling dismissed and poorly served. My shuttle service and driver was great!

I did share my observation with the gentleman that checked me in and he appreciated the feedback. Whatever happened to remedy that situation - kudos because the express service was not real express in the past. Thank you!

Brought my car in for oil change and alerted service to one tire with low pressure. Told them I had a long car trip ahead of me. When I left the tire pressure was still low on one tire. I went back. They said they had checked it and filled it. Said it would take time for the car to register new tire pressure. Baloney. One day later still low tire pressure. Went back and waited a long time before they admitted there was a nail. I told them right up front I had a 14 hr car ride ahead of me and needed to find out what was wrong with the tire. They failed to actually look at it and left me at risk of a flat tire on a long road trip. I am Very frustrated after spending so much on a car at your business to get such poor service.

The skid plates were poorly attached following an engine repair in April. The bolts slowly came loose over the past few months until they finally came loose while driving. Thankfully at slow speed, this could have been tragic if they fell off at interstate speeds. This is unacceptable quality control. I requested an oil change while the vehicle was there. It was not completed. This is the second time in 4 oil changes (50% of the time) that the oil change was not completed despite being requested. Now two days later I’m taking time out of my day to get an oil change rather than having it conveniently done as part of another maintenance appointment. Overall very unhappy that the vehicle was improperly reassembled after maintenance and annoyed that a simple oil change was not completed as requested.

I've tried making an appointment to get my oil changed and any other milestone maintenance items, but they always push you to use the express lane. It has been painful in the past, because there are usually a couple vehicles waiting outside, so you know you will be stuck there an hour or so. Friday was a nightmare. There were 2 cars in front of me outside and 1 inside. One of the techs came out and explained some changes, so it may take a little longer today. It was there before 10:30, I left the dealership at 12:45. Can't I just make an an appointment, drop it off in the morning and you call me when it's done? I don't care if it's 5:00. There is nothing express about the express lane.

My experience was very disappointing. I called and left the advisor an voice mail that i would like to schedule my vehicle to have new tires plus a service on 10/20. I didn't receive a call back so on 10/21 I scheduled the appointment thru the app for 10/24 at 1:30. I listed 5 items that needed to be addressed including, tires, oil change, and interior lights that stayed on. Upon arrival on time for the appointment, I also showed the advisor an email that I had received from the vehicle with a potential problem with the starter or the battery. I was told that there was a couple ahead of me but they'd get started as quick as they could. He also told me since I hadn't specifically talked to anyone that the tires might not get done. At 2:30 the advisor asked me if I was also getting an oil change and said they should be starting soon. I was asked questions and pointed out the codes that were on the computer. At 4:20 the advisor said the battery tested bad but that they were unable to replace it that day because it was too late in the day. He also stated that i wouldn't be charged for the diagnostics done. I purchased the extended warranty when the vehicle was purchased brand new at THIS dealer. When I went to the counter to cash out, I discovered that the tires weren't replaced either with the same excuse, we didn't have time. I was also disappointed by the sales staff. I had received an email from Buick with an offer to test drive a new vehicle and receive $50 credit towards a service. When I approached a sales guy he said he would just validate the offer since I wasn't interested in purchasing. (his words - not mine).

Over the course of the last 6 years my family has purchased at least 5 if not 6 vehicles from Billion. While the selection is nice and price fair most of the time, the main reason we have been back is due to the salesman we have had. Jesse McGraw is hands down the main reason we come back to Billion. With him on your sales staff we will be back to get our next vehicle from him as well. We did not know Jesse before we bought our first vehicle, but we feel like we have gained a family member with him. I hope he will get to see this comment Thank you Jesse, you have changed how i look at “car salesman”.

Brian Haier, service consultant, and his team always do a good job. Unfortunately we are having an issue that they cannot fix. We ordered a new Chevrolet Tahoe Premier in 2024. We have had a number of computer problems. We had a drivers side mirror that would move on it's own and not stay in place once it was set in the driver memory. Brian and his team worked directly with the GM engineers. After a number of service visits the GM engineers decided that the Tahoe needed a new switch. As of now the mirror is working. Ever since day one of owning the Tahoe, the radio has cut out periodically and then come back on. Brian and his team again have completed every GM update possible and the Tahoe radio still cuts out for a few seconds and then comes back on. The auto stop button has to be pressed every time we drive it. The outside temperature reading is often incorrect as well. I give Brian Haier credit for working tirelessly trying to get my new Tahoe to work the way it should but I am very disappointed with this vehicle. We have been very patient as we have worked through all the issues but it seems that it's time for GM to step up and help us favorably trade for a new GM vehicle. Tom Tiedemann

Bought my 2023 GMC from billion 4 or 5 months ago and I’ve had two instances where it has given me error codes/dashlights that made it unable or unsafe to drive. This surprises me because I was told all your vehicles go through a thorough inspection prior to sale. First service cost me 400$ for a sensor that needed replaced. 2 weeks later my breaks stop working because of a loose or burnt out wire. That cost 1200$. I’m also upset that I buy a 53000$ pickup with you guys, buy my wife’s car through you and do all my oil changes and rotations with you and when my pickup is broken down in the shop that you guys sold me you can’t even give me a loaner vehicle so I am stuck without any transportation for as long as it takes to fix my vehicle. I will no longer be using Billion.

Scheduled app't for 7:30 am. I brought truck in at 7:30 and was provided a ride to work. I called early afternoon same day 2 times to the numbers provided and left messages. I called a third time and was told "they are still working on it". I got a ride from a fiend to check on the truck after work about 4 pm. The truck was still parked in the lot where I left it that morning. I was told they didn't have time. Then the service manager Danny told me to call when I got to work the next morning and they would come get my truck from my work place. I called the numbers they gave me and received no answer. Finally I called the GMC main number and was transferred to a voicemail 2 times. I then called a direct number and was told that Danny was out for the next few days. I had one of my employees follow me to the dealership to pick me up after I dropped off my truck later this second morning to make sure I had a ride back to work. I called mid afternoon to check on progress and was informed of the minor issue of a bad spark plug and was promised a call when they were done. Finally, I did receive a call that it was complete and asked to be picked up. I was picked up in a timely manner and paid a hefty $389.53 for a spark plug change. I understand that Travis the service writer was quite busy as well as the techs, but the part about not having my truck picked up from work after being without it for a day with no good reason and nobody having any idea about what I was promised for getting my truck picked up was inexcusable.

Paperwork went smoothly. Car was cleaned and ready for us. Sales staff did great job at explaining the various features of the car and how all the buttons & options on the dashboard and controls worked. People very friendly and efficient.

I’m not sure whose fault it was but it took several days for the part to be delivered to the dealership. That meant I didn’t have my truck over the weekend. I should’ve had it Thursday.

Service Advisor Austin Griffith did a great job of getting me in and out in reasonable time frame and did a good job explaining the situation. Unfortunately, the problem is known to GM and they say they are working toward a solution. Based on my past experience with my 2019 Chevy Traverse which also had a known problem that GM was "working on" and which ultimately cost me a $1,000 to fix because GM never treated it as a recall, I don't trust GM to ever come up a solution to this problem with my 2024 GMC Canyon.

Wonderful experience with Tom! I left the lot and drove less than 10 miles when the heck engine light came on. I went back to the dealership on Monday (I bought it on a Saturday) & they got me right in to fix the issue!

I was told the part had no ETA but when I called GM myself they said they had the part and it wasn’t even ordered until 2-17 (a month later) and then GM shipped it out on 2-18. They said they had the part and it was never an issue to get it. Communication was very poor and rude!!
