Only needed an alignment. Price was 139.95 already too high then he tells me that price is already discounted and I couldn't use my coupon. To make matters worse my tires weren't inflated before the alignment I had to get air at a gas station the same day. Lesson learned.

Falom and the rest of the team made this a most pleasant buying experience, and were straight forward from the onset regarding the purchase of a 2021 Sierra Denali. The no pressure approach in what seems a difficult market was refreshing. Well done.

This was the 5th vehicle I have purchased at Koons Honda/GMC. I am a return customer because the buying experience is pleasant, efficient and the sales team is great! So courteous and professional. They have never pressured me nor tried to sell me something I would not be happy with or unable to afford. I will definitely continue to choose these guys for my automotive needs for both sales and service.

Recently, I needed my driver seat trim replaced. With a few hiccups in getting the trim ordered, once I connected with Terry, the Service Manager of Buick at Joyce Koons, my trim was changed very efficiently. Dealership arranged a loaner, picked up my car from my house same day, dropped the loaner for me to use and brought the car back same day and picked up the loaner. Excellent service that day. Joyce Koons keep up the good work. THANK YOU.

Terry and the service department at Joyce Koons were amazing when we needed a miracle on a Sunday afternoon. When our family was driving from Florida to New York on Saturday, we stopped for the night in Lynchburg, VA and realized the tire was losing air. On Sunday morning we were hoping to get the tire repaired or replaced, and get back to NY that day. However, we found the 22" rim on our Yukon XL was cracked. We got the spare on and working, and found Joyce Koons service department was open on Sunday. I spoke with Terry, and the miracle began - they had our 22" wheel in stock! I

Way overpriced even though prices are clearly written within shop. Charged a $45 inspection fee, which was not outlined prior to work being completely that turned an $80 oil change into $126. Thankfully I had GMC points to pay for the service. Will not return.
Edit: GM repair shop called and was confused with my complaint and why I had a problem with the final bill. Well, it was $125 for a simple oil change and tire rotation. Thank goodness I had GMC points to pay for most of the bill. Folks, save your money, buy your own oil and attend YouTube academy to learn how to change it yourself
