Brilliant Car, expert servicing
Excellent car, just done 122K and runs like a dream, had it serviced regular by brilliant guys at the general motor company in Stockport in UK. Didn't want to trade in when lease finished. Looking to get many more miles Peter Gilligan

Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

Simply Amazing
This is my second time purchasing a vehicle from Comet Auto Sales and I felt the need to leave a testimonial anywhere i could. I purchase vehicles about every two years. I drive to much to lease and drive to much to hang onto something so I've done the 'car buying thing' a few times. Nick was my salesperson on both accounts and he is very straightforward and knowledgeable. Both cars I have owed were beautiful, reliable vehicles. The first vehicle I purchased here I found out a few days after the sale that the lender I financed the car through was offering a 3 month 'delay' in pay and I called the dealership immediately to see if we could re write the loan to account for this - Nick took the time AFTER the sale to re write the contract to account for the 3 month delay in pay and FedEx'd the contract to me (on their dime) so we could make sure the loan went through in time. On the second and most recent occasion, I had purchased a BMW from them. They had put the vehicle through a shop to have the inspection sticker put on (please note the auto body shop is an independent business from Comet Auto Sales - they are in the business of buying and selling cars, they are not an auto body shop, so they outsource this task). The shop noted the car was great and I drove off. I had made an appointment with a local foreign car shop within my area which was about 2 weeks after the sale. This shop noted that I needed rear breaks and rotors. I contacted Nick at Comet Auto Sales and they paid for the whole thing (I was quoted $650 from several shops so it was not a small repair). I could not be more impressed and I would recommend them on so many levels and for so many different reasons. Deirdre
This car is in very good condition!
The comfort level, the interior and exterior, the wheels, rims all are in great condition. I really like this car. Best Purchase ever!! Good place to buy a car.

Ali was good.
Ali was good. I had the financing secured online as well as a couple others to choose from that Ali provided.. Made sure the car was in tip top shape before delivery and handled everything at the RMV. Extremely satisfied with the process.
Best car i have owned.
This car is luxurious and sporty. Everything you want in a car. It is the best car I have owned so far. I am very happy with it. I just had the 30K service. It was expensive, but its Audi. You get what you pay for.

Foley Motorsports - Review
I’ve been looking for a Cadillac Escalade for over four months and with absolutely nothing local to my area of Upstate NY I felt the need to explore internet searches. From the moment I first saw this vehicle on Cars.Com I was impressed with the ad presented by Foley Motorsports. The video content, detailed description, financials and pertinent data was all at my fingertips for review. My first e-mail correspondence with salesman Greg Ostrander was impressive. With attention to details he was able to guide me through most elements about the vehicle with no second guessing or (let me check on that) type of response. He clearly is understanding of clients needs and looks to provide whatever is necessary to make someone comfortable with the purchasing process. Ultimately I purchased the vehicle this week and was able to get it home to my residence today. Just looking at it in the driveway gives me a sense of accomplishment that this search process is over and I’ve scored on a great deal. It’s hard for me to explain how this car buying process was the most pleasurable time ever. I just wish this dealership was in my home town.

Incredible Service
I bought a Volkswagen Jetta today- the man who was assigned to handling my purchase was incredible. Superior Customer Service skills. The process was painless- and again the service was fantastic!
Better than my first Audi
I have owned this car for just over a year. No mechanical problems, very fun to drive. Took it across the country, very comfortable for driver and passenger. Loves to cruise at 75-85 mph and will go much faster. I thought I got a great deal on it. I paid half the sticker price and it had under 10,000 miles on it.

Great experience.
My experience with Foley Motorsports but specifically with Fabricio Machado was outstanding. From my first email to him about a specific car, he was professional and courteous about my trade and purchase of the new car. The dealership is top-notch! I feel I received a fair value for my trade and an excellent value for my purchase?

If you are in the market for a car I would highly recommend DC Motors. My experience with the DC Motors team (Derek, Chris, and Jay)was excellent! They were responsive and answered all my questions. They were friendly and knowledgeable. My car purchasing experience with DC Motors was five stars!
Beautiful Meh
Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.

Alex was outstanding from start to finish.
Alex was outstanding from start to finish. He was patient, knowledgeable, and genuinely accommodating throughout the process. The entire team was professional and worked hard to help us get the exact vehicle we wanted within our required down payment, which we truly appreciated. The process did take longer than expected, mainly due to paperwork and waiting but the staff professionalism and positive attitude made it much easier to get through.
Pure luxury
This Audi is beautiful, inside and out, with genuine wood in the door panels, dash and center console, soft leather seats, and a massive amount of red light illumination throughout the front cockpit, that is fantastic while driving at night. The exterior is sleek and stylish. The ride is smooth, however the low profile tires do ruin some of the ride atleast on kansas roads that are far from smooth. The engine has no vibrations and suspension seems tight . All in all this is as close to perfection as it gets, German cars are the best.
