2021 Challenger
My wife and I live in Texas. So obviously there are thousands of dealerships from here to Chicago but after talking to DJ, we decided to take the drive out here. We had such a great experience with DJ. If you are looking for a stress free car buying experience go see DJ at Midway Dodge
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

It went well, but I didn?
It went well, but I didn?t get what I wanted for my trade in. Good place to shop for new vehicles. Reputable dealership. I was very satisfied with my purchase.
Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

They go above and beyond, making buying a car and enjoyable experience! Highly recommend! Fleet department is the best! Eli and Sarah are my favorite!
Unbelievable towing capacity.
The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

Easy to deal with.
Easy to deal with. Texas was very knowledgeable and caring and listened to my needs. Fast easy process highly recommend! Great place to do business!
Capable truck with the right options
Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

I brought ny Cherokee Jeep in for an oil change. Derek is very knowledgeable and extremely professional and explained that in 60x miles the jeep will get a thorough check up. Even the oil change had many things checked. They are the dealership I want all.my service to go to. I trust them to tell me what's really going on. Thank you Derek and Rairdon Dodge and Jeep.

We had a wonderful experience at Unique Auto Group. We found the vehicle online and called to say we were interested. They had the vehicle pulled out and ready. The price was excellent and as advertised. No hidden fees or problems. Amir was great! He helped through the sales process, and everything went without issues. I highly recommend buying a vehicle from Unique Auto Group! We will definitely buy from them again!

Purchased a 2024 Ram 2500.
Purchased a 2024 Ram 2500. The sales staff was excellent to work with and very personable. I would recommend doing business here and will try to in the future. I flew there from Nebraska to make this purchase and was nervous. When I got there I soon realized I had made the right choice. Sales personnel were not pushy and very down to earth and didn’t not try to force anything on you that you did not want. After I bought the truck I jumped in it a drove home six hours with no regrets and no issues on the truck I picked.

EASY TRANSACTION, GOOD TRUCK
I bought a F350 online thru Cory. I bought it unseen, just pictures. I had the truck picked up by a friend and brought to New Hampshire. Truck is in very good shape, and I got it at a great price. Cory was very easy to deal with. Next time I need a truck, I will call him.

Service+
While my car was being serviced on Aug 14, I had a really fun conversation with Ryan. After servicing, I investigated the lot & found a car I really liked. When I was able to, I talked with Dwight Fouts about the car. He figured a deal for me that got that particular car in my garage. My husband & I have dealt with Ferris for about 30 years & I will continue to deal there!
