Long after I made the decision to buy the two cars one
Long after I made the decision to buy the two cars one month apart. Both sales people that sold me a car apiece did a good job and were very friendly.
2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

my wife and I were looking for an MDX, had been looking
my wife and I were looking for an MDX, had been looking several weeks, when we recently stopped by Jerry Hunt Auto...we were assigned to salesman, Axel Camargo, who was friendly, polite, helpful, and knowledgeable about the car we desired. He found nothing that day, suggested close alternatives,etc. but we chose to wait. Axel continued the hunt for what we wanted, which showed up on Cars.com and was at Jerry Hunt's. Alex was called by us, showed us that car, not pushy, though, and we made the purchase. He followed up with us a few days later, which was nice of him. Zack, who did the paperwork, was also very polite, and thorough...would recommend Jerry Hunt Auto...ps, and ask for Axel
Best truck I've owned yet
What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

This is the first experience of buying a new vehicle that there were no games. MJ was my salesman and was unbelievable…I told him what I wanted to make the deal and he and the dealership delivered! I’ll be back for sure.
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

Mike McLean and the crew at Corwin Motors did a great job! Buying a car remotely, 16 hours away made me nervous. I'm confident that all will work out.
So far have loved my 2020 2500 HD 4x4 diesel
I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

Unlike your typical car dealership!
Unlike your typical car dealership! These folks got it going on. No pressure, knowledgeable, insightful, helpful and willing to work with you... I've been to dealerships up and down the Treasure coast, not saying there aren't other great dealerships, but this one stood out among most. My experience with the salesman Edison was anything but high-pressured. He was low keyed, compassionate, helpful and insightful. The manager Phil was extremely patient, friendly and accommodating to the point of matching me to my next ride. Soooo unlike the dealership I went to that was the diametric opposite... Bev. The finance officer Lauren was a delight to work with in closing out the paperwork which is always such a dreadful part of the process. If you're interested in purchasing a vehicle without all the hassle that comes with it... Sunrise is the place for you.

We drove 5 hrs to purchase our vehicle and it was well worth the drive. We bought a used car and we were treated like we won the lottery and we’re buying a dozen new ones!! Brad Arrington was the best! Everyone we dealt with was top notch. Who knows, someday we may drive 5 hrs just to come back. The Browns Gainesville Texas

Only negative I could say about the company and it isn?
Only negative I could say about the company and it isn?t really a negative is that they don?t accept my vehicle warranty and other dealerships do and it has been proven to pay out on claims. Other than that the service they offer is great

Probably the best vehicle buying experience I’ve ever
Probably the best vehicle buying experience I’ve ever had. Mike Pecha was my salesman. He was professional, courteous and super knowledgeable about all aspects of the vehicle. He made me fill comfortable during the entire process and explained everything thoroughly. We took the vehicle for a test drive where he demonstrated all of the vehicle features in great detail. I would trust any of my family and friends to deal with Mike. The dealership also has a huge inventory of just about any vehicle you are considering. Personally, he helped me get into a beautiful GMC Yukon Elevation. Probably the nicest vehicle I’ve had the pleasure of driving. I see why he comes highly recommended. I will continue to get all my vehicles from Mike at Trent. Nicely done and thank you for making it an enjoyable experience

Had so many bad experiences with supposed deals online just be be lied to when arriving at the dealership. Mark was great to deal with and was up-front on pricing. We had a deal in place online and when arriving at the dealership, there were no games. He backed what he said and because of that we purchased a vehicle from him.

I had an excellent experience at this dealership! Though it took a few hours, which buying a car normally will, my sales person, Evans, made sure that I had snacks and water if I needed them. As a first time buyer, they helped me through the process and got me the best deal. I was able to go home with a brand new car! They explain everything so well. Special shoutout to Evans, he did a great job and was very helpful! I definitely recommend!
