Good customer service and the buying process was smooth.
Good customer service and the buying process was smooth. I like to shop at businesses where people smile, and understand that you work hard for your money. When I make an investment, I want to spend it with a company who welcomes me and appreciates my presence.
This truck has a jerk when changing gears sometimes.

Just a GREAT experience from beginning to end!!!!
Today was the day to pick up my car! A week ago, after just a day of discussions, Sammy and Aaron made what had been a terrible mistake I had made a couple of months ago into a WONDERFUL sales experience! And THIS during a pandemic when I was having to try and correct my mistake while sheltering in place at home. You see, I have always driven foreign vehicles and SUV's since 1999. And there have been a lot of them, just never an American car, except for my play Jeep. But, our family needed a larger vehicle and we had decided on a Navigator. In January, we went large and purchased a Navigator. Unfortunately, we didn't go large ENOUGH... We needed a Navigator L to accomplish our needs. You can imagine the pain of this realization given the depreciation that takes place the moment you drive a car off the lot. AND I didn't figure it out for over a month. Well, I had spent almost 2 weeks negotiating with the dealer I had purchased my previous vehicle from as well as EVERY OTHER Lincoln dealer in the Metro-ATL area...All not willing to help me with my problem and at the end of the day leaving me to feel as I was going to have to live with my mistake. Then Sammy called ME! And within one day we had worked out a deal for a trade that I could very definitely live with. In fact, one that I could even be excited about. And the pricing for my trade (granted it was almost new) was done site unseen. AND when I got to the dealer there was NONE of the haggling or you didn't tell us about this, etc. Just fair-mindedness, and during these dangerous times...A SAFE environment! I couldn't have asked for more. And when they needed to do some work (tinting, clear-bra, etc.) work to my new vehicle, I was immediately placed in a wonderful loaner until my new vehicle was ready. SO MUCH Better than my last experience. These guys are doing it right and have earned by service business. Yes, It's a long review, but these guys deserve it. I look forward to meeting my service adviser and working with these guys for years to come! AND I can't wait try the Pick-up and Delivery Service!!!!!

The customer service was great.
The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.

My experience could not have been better.
My experience could not have been better. Terrie was our sales rep and she was FANTASTIC. She made me feel like I was only sale for the day. She took the time to explain anything I didn’t understand. Took us on a great tour of Beaver also. I don’t think I would have bought my Tacoma from anyone but Terrie. Thank you.

My first time at this location and was a bit concerned
My first time at this location and was a bit concerned b/c it was crowded however that is the norm and they are used to it. They handled the crowd with ease. They got me in and out. No complaints regarding my service rep, nor the job performed on my car. Will be returning for sure.
