We recently purchased a 2022 Ford Explorer.
We recently purchased a 2022 Ford Explorer. A service light came on, and we brought the vehicle in. Excellent service! Kept us informed of the problem and when parts were available. Everything ended up covered under the extended warranty. We were extremely pleased with the service department!

The reason why I am writing this is because I know the mileage is off because there is no way I can drive 100 miles in the city in one day it's not possible. This is a complaint for me because I feel it needs to be looked at.

Doug to the rescue
My guy was out delivering a vehicle so Doug stepped in. Sold me on the midnight Altima. Can’t wait to buy it this weekend. Yay Doug.
Love this car!
Love this car! We were sizing down after three JEEP grand Cherokees and a Buick Enclave. We finally went with something more like a car. I am always attracted to more interesting and unusual (wouldn’t know it by my last four cars!) and when I first saw one of these I was so intrigued I had to research it. Then search the country for the color and options I wanted. They are a bit rare! But they drive like a dream. And always garner interest among other drivers. It is quick, has been extremely reliable and carefree. And the sure-footedness of all wheel drive has been great in the rain and snow of the Pacific Northwest. Plus I’m getting over 30mph flying across the west on regular unleaded! And it is cavernous, both in overall capacity, but even for my 6+ footer boys in the back seat. I haven’t been as happy driving a car since the sport cars of my youth! Only giving it four stars in comfort because the drivers seat is a little too narrow for long hauls for my larger frame. But the fun makes up for it!

Love this dealership!
I have been a loyal customer to this dealership for repairs and car purchases for years, because I have tried others and KC Summers really is the best! Excellent quality of service, honest and knowledgeable staff, willing to explain details and work with your needs, great variety of vehicles, community involvement, and most of all their customer service is the definition of going above and beyond! Their prices can be a little higher than their competitors, but it is worth it to have a friendly, no hassle, flexible experience for every purchase and repair!! If you've never worked with them before, I think you'll be pleasantly surprised!

I have bought many Toyota here and always am treated exceptionally well. I refer all my friends and family.
My only complaint is that I cannot seem to close the door
My only complaint is that I cannot seem to close the door mirrors. Small complaint and not really a flaw but cosmetic. The car is amazing. It has plenty of room and acceleration. It is comfortable and luxurious too.

We’ve had the best experience purchasing our new car
We’ve had the best experience purchasing our new car here. Brandon is super friendly and makes the buying process easy. He’s very knowledgeable, explains everything very well and gets the job done right the first time!
Supeerb Automobile
What a superb automobile. This is what I have wanted in a long time. It has more bells and whistles than I really need but it is very nice to have them. Everything I marked above is definitely true and more. I would highly recommend this auto to everyone interested in buying one. Believe the right ups on this auto that others have also made.

The hidden gem Buick Encore GX
I know that here in Northern California, Buick isn't a very popular brand, but that means I was able to get a stunningly good deal on my new '23. I traded up from a low mileage '18 Buick Encore (not GX), and at the time of the transaction, it had a remarkable trade value. My dealer did a outstanding job on pre-sale prep and delivery. My sales rep answered my every question. I enjoyed the prior vehicle, and feel this new one will give me the same kind of driving experience. My added safety feature is the front accident/pedestrian avoidance and lane keep assist. I haven't had to use either yet, but feel good about having them aboard. This Buick strikes me as a hidden gem, full featured but still available at a price point that blows the other comparable Asian built imports out of the water.
