This time around I was impressed with the service I received from my advisor Steven Coyne and the work got done in a timely manger. The work being performed was under a mechanical breakdown claim as well as my lifetime oil contract and I had no billing issues or any issues with the work done. Thanks Chevrolet LITHIA.

I went into Corwin looking for a specific vehicle. Bailey Reed approached me and I told him I was interested in a truck on the lot. He went the extra mile for us to get what we wanted. He made it easy for us, I appreciate him a lot, he did a good job for my wife and I. This is the second time we’ve bought vehicles at Corwin, it’s our go to place for an honest deal.

Went to just look at new cars, Wrong idea!
Went to just look at new cars, Wrong idea! We met Dexter and he was the best car salesman I’ve ever dealt with. He wasn’t pushy, He let us look, and then he gave us a few cars to look at at what he thought we would like. Found a car in a matter of an hour. Went back the next day and boom it was ours. They had the fastest and the best system at purchasing a car, simple and easy no more back-and-fort smooth and easy and I would recommend Them hands down.

Initially my wife and I had just planned on purchasing a
Initially my wife and I had just planned on purchasing a car for her since the lease on her current vehicle was due to expire. Chris Warr was the sales consultant who helped us when we arrived to test drive a few different models. My wife wasn?t really sure if she wanted an SUv or a truck. Chris was patient and friendly. He made us feel comfortable and not rushed to make a decision. He even went as far to take us to see a model that was being displayed for a car show so my wife could see all of her options. Ultimately she purchased a 2026 Terrain AT4. Every one we encountered was friendly, helpful and answered our questions and made the process of purchasing a car simple and as stress free as possible. I would like to mention Ben Gallegos for helping us with the additional accessories my wife wanted. Marian Ciubotaru for walking us through the financial side, he answered all of our questions and took the time to make sure we were clear on the paperwork and pricing. Frank Pereira was our initial contact when we scheduled our appointment. He was friendly, listened to our needs and stayed in contact through the entire process. We are definitely happy with our interactions, so much that I had an appointment the following day to purchase a Ford Bronco for myself and ended up canceling my appointment and purchasing a Canyon AT4X the following day. So 2 car sales in 2 days. All due to the treatment we received and to be clear feeling comfortable and not being bombarded with a heavy hand to make a decision until we were ready. We also believe we received a fair deal. In addition, I was not happy with the rims on the truck which was almost a deal breaker for me. Purely because I had a vision of what I wanted. Ben, Frank and Chris worked to find me options and Ben found the exact rims I was looking to purchase. We are taking both cars in on Friday for the accessories and they even made sure we have a car to drive while our new cars are being completed. We are grateful and not only will we be buyers in the future we will be sure to share our experience with our friends and family.

We've had a great experience with Key Auto Mall GMC
We've had a great experience with Key Auto Mall GMC purchasing our new 2025 Acadia. Brian MacGee was wonderful to work with along with General Manager Theron Maring and all the other great staff. Brian especially has spent a lot of time going over all we need to know about how this car works and has several times answered more questions since we purchased the car a week ago. He helped us purchase new cargo mats and get the protective coatings on the car, inside and out. Brian has been professional, friendly, and so helpful to us. We highly recommend Brian and the Key Auto Mall GMC team and will definitely consider them for our next auto purchase.

Working with Drew at Briggs Nissan of Manhattan made the car-buying process remarkably smooth and stress-free. From our initial interaction, it was clear that this dealership operates differently—prioritizing genuine relationships over high-pressure sales tactics. Drew took the time to understand our needs and guide us toward the right vehicle, without ever making us feel rushed or pressured. In the end, we felt confident that we reached a fair and mutually beneficial agreement. Gabe in the finance department further reinforced the dealership’s commitment to a seamless experience, handling everything efficiently and transparently. If you’re looking for a dealership that values trust, respect, and long-term relationships, I highly recommend connecting with Drew at Briggs Nissan.
