Our Reviews
We appreciated the quick service and tire replacement at a reasonable price. Cam in the service department is very professional and knowledgeable, and easy to work with.
Always top notch service. I’ve never been dissatisfied or thought the prices were too high. I don’t trust anyone else with my vehicle.
To this day, it was the best and quickest vehicle purchase of my life. No waiting around all day. I knew exactly what I wanted, got it at the price I wanted, and was in and out in about 2 hours. Awesome team of people working here.
I have worked with Colt Anderson over the years, and he is the best there is! He had all paperwork ready when I came into buy my 2022 GMC and was very thorough with explaining how all the features work.
I finally git my truck back after 5 weeks. Did not like that 1 bit and relying on others to get me to my job out of state. Need to have a loaner in circumstances like this.
Very easy and smooth transaction. Scott and John were fantastic. A no BS experience and no traditional auto purchase games.
Quick, I love having a appointment, in and out. Very nice employees who are friendly and helpful. Facility is clean, well lighted, comfortable.
They made a special effort to squeeze me in before a long trip. Always accommodating, they make my life easier!
I basically purchased the vehicle over the phone with Jamie Wittman's excellent help. The dealership came highly recommended and now I know why.
I will definitely keep doing business here! What An Amazing team. The sales, financing and management staff is on point. Everyone went above and beyond to help out. Great job down there!!
Bryon Miller, and the rest of the team made us feel like family. The best experience from begining to finish me and my family has experienced ever. Bryon made us feel like family, help us through out the process and we will reccomend him and this dealership to all those we run across for car needs.
Cam was great help and Chris who worked on my truck did a great job. Thanks to both for a great job! Richard
Great experience. Colt kept me informed from start to delivery. Very good instruction when I picked up my SUV. And he continues to help via texts.
Quality service, especially from Mr. Swedberg in the service dept. He listened, followed through, and I couldn’t be more satisfied with his efforts.
I can't say enough good things about this dealership. Everyone from Jim Casey to the sales and service staff are the best I've ever dealt with and ANY dealer. Shawn Smith, Sales Mgr., Cam Swedberg, Service Advisor, Bryon Miller, Salesman are the best. Visit other dealers in Cheyenne at your own risk, then go to Halladay with cash in hand.
It’s always great to see Cam! He does a great job explaining what is going on and he very personable! Give that guy a raise! The repair came just in time because it poured rain the next day!
Fast and friendly service. They have done a good job with my crook since I had bought it. Would recommend going to them.
Very friendly Did a quick and great job and did a multi point inspection of vehicle and gave me a car wash
Great Customer Service! Cam is always going above and beyond! My car is always in and out in a timely manner.
Not feeling pushed in any way, Bryon was very helpful in finding what we were after. He very easy to work with and able to answer any questions without hesitation.
Always good service. Clean facility, easy check in email reminders on appointments or text message reminders. Very good coffee in the waiting room.
Ease of scheduling a test drive. Professionalism of staff. Positive energy. Willingness to help. Buying a car from a distance and having it delivered! Everything done over the phone! Everything about this transaction was above expectations!
Fast and done right the first time. Everyone was courteous and very knowledgeable. I will definitely recommend and use this facility again if needed.
Friendly, convenient service. The buying process was so great - no pushiness in sales at all, which is always what we look for. Took our vehicle in for regular maintenance which was quick and painless and less expensive than other places we have used. We will definitely be back.
Jeannie is always so pleasant to work with. Every time time that I have been there, she is always eager to help with whatever work I need done.
