Our expectations were beyond met.
Our expectations were beyond met. Isaiah was extremely knowledgeable,patient and a joy to deal with. We were shopping for our son's first vehicle. We will definitely be back to see Isaiah in a year or so with our daughter. As well as all of our families vehicle needs here on our. I highly recommend your dealership. Also to request Isaiah. I'm sure we would have had a great experience with any of the sales representatives. It was a very warm and comfortable atmosphere. We out very happy and look forward to future dealings. Thank you again Isaiah.

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Great place to buy a car
Tom was polite. And very informative. Not pushy and answered all of pur questions. I ended up buying a car that was discounted. 10 out of 10.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Midway Automotive
They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.

Overall Great Dealership
My first Cadillac purchase was a pleasure in 2020 with salesperson Dave Robinson. I have been having my oil changed a few times since then. Renata in the service dept was great and the waiting area is comfortable with workstations, water, coffee, and snacks. They even washed my car. I highly recommend this dealership.

Mister
The initial day we went to look, we were very happy leaving. We found something we loved, and Deb was amazing! We went back to do paperwork a few days later with Roger, who was also great to work with, and were told we could pick it up 24-48 hrs later. Friday came and there was a slight mix-up, but Eric and Deb took full responsibility for this mix-up and worked with us to fix it. Deb came in on her day off and we drove our car home the next day. Cannot say enough great things about the customer service here! Thank you for making our car-buying experience a good one!
