I've traded in my old Mercedes for a newer model.
I've traded in my old Mercedes for a newer model. From the moment I visited the dealership everyone was very nice, friendly, courteous and professional. They took the time to show me a few cars I was interested in before I was able to make my decision. It has been a fantastic experience and a very smooth transition from beginning to the end, thanks to guys like Joel, Oscar, Mike and Jhonatan. They have made my shopping and driving experience so much smoother than I ever imagined, and of course they made me an offer I couldn't refuse. I strongly recommend the Bishop Maserati dealership for all your car needs. These guys are the best!!!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Got in touch with me very quickly when I messaged. Very easy to work with and the truck I bought was priced to move. Easy buy and great experience overall!
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.

Overall great experience!
Had a great experience from start to finish with CPO Department at Huffines. Clear and timely communication leading up the sale and a short, direct purchase process. We noted a few minor items after the sale and the team was very responsive and helpful in getting all items resolved. I would definitely consider purchasing from Huffines again!

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! 👍🏻

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.

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!

I was asked when I needed my truck back, I alex for 2pm. I never got a call, and when I went to the dealership at 3pm because u didn't get a call back, I was told my recall was not done and it would be 45 minutes longer. Very disappointing the lack of communication. There service department was slow and I never got av return call. I was not able to wait so had to take my truck. I would continue to go to Ewing but they will not take the service plan I bought from freeman when I purchased my truck. Keep in mind we've purchased five trucks from freeman in the last two years.
