Tin Tran is the kind of service adviser every dealership
Tin Tran is the kind of service adviser every dealership should be proud to have. He’s helped me on multiple visits with thoughtful updates, prompt follow-ups, and has always taken the time to point out any coupons or specials that could help me out—even when I didn’t know to ask. What really sets Tin apart is his integrity. I’ve never felt pressured or upsold—just supported by someone who genuinely cares and wants the best outcome for his customers. That kind of trust and consistency means a lot. He’s gone above and beyond every single time, and both Rusty Wallis Honda and I are truly lucky to have him.

I look forward to buying here again
We were pressed for time & needed a good, reliable truck. Our young son was leaving for Illinois in a few days. We almost literally ran into Kevin on his way out of the gate-Lol! He stayed a little late & showed us a great F150 trade-in he had just gotten & made a great deal out of it for us. He had it detailed, inspected & mechanically checked out for Josh to get on his way. I believe Kevin was sincerely invested in our son’s well-being for this road trip. Of course, Josh made it without a hitch! Thanks again, Kevin & God’s blessings on you, your family & your great business! 👍🏻
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

At first, I was hesitant about going to Auto Place Inc.
At first, I was hesitant about going to Auto Place Inc. due to the past reviews that people have written. I decided to take a chance with them, which was the best decision. When I arrived, I showed them the three trucks I wanted to look at, and they handed me the keys to them. They let me take my time looking at them and test-driving each truck. The team was not sitting over me like most dealers do. If I had questions about something, I went into the office to ask, and they answered everything I asked. I could take as long as I wanted and did not feel pressured to buy a truck from them. At the end of the day, I bought a 2015 Ram from them. The one thing that came up after I purchased the truck and was driving it home was that I started getting a vibration in the front end when applying the brakes. When I got home, I checked the brakes out and saw they were worn and needed replacement. I knew I bought the truck “AS IS,” but I still sent them an email about the issue, and the following day, when they were open, they called me and said they were sorry to hear about the issue and we wanted to take care of it for me. They did not have to consider that because I bought it “AS IS.” So, I drove it back to them, and not only did they replace the front brakes and rotors for me, but they also replaced the back ones. That is fantastic customer service, and I would recommend Auto Place Inc. to anyone looking for a used vehicle. The one negative thing I have for them is that they do not offer a CARFAX report on the vehicle.

Outstanding from start to finish!
Outstanding from start to finish! Brian Prosser helped me with looking and leasing a 2026 Equinox. There was no high pressure tactics or gimmicks. He took his time to show me the vehicle and drive it. On the purchase price, again...no gimmicks or games. Once the price was agreed upon and the trade in valued, the deal was complete. Nico Anwary was the finance advisor we used. We had used Nico before and preferred him to anyone else. He was very straight forward on the leasing price and recommendations of care for the vehicle. No games/gimmicks. He took his time and answered all of my questions/concerns.

I had the pleasure of connecting with Hopper MotorPlex
I had the pleasure of connecting with Hopper MotorPlex last week after a friend had told me about them. Wow, while I’m a car guy, purchasing a daily driver is not my idea of having fun. The experience rein-instilled by faith in purchasing an automobile at a local dealer. Gary, Randy and the entire team were professional and brought a transparent and a no nonsense approach to my selection and purchase. Check out their impressive, clean and varied inventory….. you will be glad you did! Until next time!
