Happy customer
The sales team was very prompt on getting back to us when we inquired about our vehicle. They were also very informative on the product and were able to answer whatever questions we had for them. Once we were to the point of agreement on the price of the vehicle they were always helpful with the rest of the sale all the way thru the sales contract. This was very helpful as we are in another state and everything was over the phone and emails. Thanks again, The Woodruff’s

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!

Amazing car buying experience!!!
By far the least amount of time spent purchasing a vehicle. We knew the numbers, and got all questions answered in a matter of minutes. They brought the car closer to us and had all paperwork ready to go. It only took 10 minutes and we were on the road in our new car. Well done!

Sales and finance teams were extremely flexible and
Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.

There’s a reason people leave the Peters sticker on their car after they buy one and it’s because of the top quality customer service provider by the caring team at Peters. The online shopping experience was easy and fun compared to the pressure of our last car buying experience. Now our family fleet has Peters stickers!

Friendly, hard working staff.
Friendly, hard working staff. Kline was professional and personable. Kline is the MAN! John was also very friendly and flexed with his ability to get me financing. Niko was also a pleasure to deal with. Overall a seamless and painless deal. We never felt pressured but we did feel welcomed. Everyone was very friendly. We would gladly make the drive up from Brighton, CO again.

We recently purchased a 2023 GMC 1500.
We recently purchased a 2023 GMC 1500. Our experience from start to finish was exceptional. The moment we walked in were greeted by Kyle the General Manager. He was friendly and knowledgeable. He hooked us up with Nick in the sales department. Nick not only showed us the car we came in to see but also found several other options that fit what we were looking for. They were able to get us what we were looking for from our trade ins. Terrence seamlessly completed the purchasing in the finance department. Not once did we feel pressured in the process. Best car buying experience we have ever had. We HIGHLY recommend GMC of Watertown!
