Awesome dealership
I was looking for preowned vehicle and found a Toyota on DCH‘s website. Tony show me the car and worked financing numbers for to make sense for me.
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

I have nothing but the best to say about my first
I have nothing but the best to say about my first experience at McMahon Ford. Sales, financing and the owners were all available and respectful. It was the best car buying experience I have ever had.
Love it so far
Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

Best place to buy a car from.
Best place to buy a car from. The guys are great and help you with everything. I am so happy I got my 2020 Acura tlx from them. Sal really hooked me up with the best price!!!!
Large yet stylish enough to carpool the Grands
We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

After a long day of disappointing experiences at other
After a long day of disappointing experiences at other dealerships, I was ready to cancel my appointment at Carcatle. Thankfully, my wife encouraged me to follow through—and I’m so glad I did. From the moment I arrived, the staff were nothing short of amazing. They were knowledgeable, friendly, and made the entire process smooth and stress-free. Their professionalism and genuine approach completely turned my day around. It was clear they cared about making the experience positive and straightforward, not just making a sale. I highly recommend Carcatle to anyone in the market for a car. You won’t be disappointed.

A great place to shop for any car
I have to say, this is my 4th stop within 3 days before I pull the trigger on the 2020 BMW X5 at Import Masters. I was surprised how I was treated considering I was way underdressed for the occasion. Most sales people would think WHAT THE xxxx IS HE DOING HERE LOOKING AT BMW X5. Edwin was very nice and made sure I was taken care of properly. All the staff are very friendly, even the little guys who are cleaning and waxing cars. They gave me all the information I need it on how to take care of the car. I highly recommend the place and make sure you don’t forget to check out and cruise around the neighborhood. You won’t regret it. xxxx a lot better than some other places I have been to. I advise you to make an appointment before coming in so they can bring it to the showroom. They have so many cars that almost stack on top of each other.
