I purchased the new 2025 Kia K4 EX during late August for my wife to help celebrate our 55th wedding anniversary, and she simply just loves driving the car with all of its modern safety high-tech features, its comfort, and impressive driving performance. I've nicknamed the car "The Batmobile" with its Aurora Black Pearl exterior paint and stylish features that make this car stand out from other sedans that are in the cost-effective $20,000 - $30,000 price range. Plenty of room inside the car, a quiet smooth ride, and adequate acceleration whenever may be needed (e.g., entering onto a highway). The car comes with Kia's standard 5 year, 60,000 mile full warrantee, and 10 year, 100,000 mile powertrain warrantee which is still very generous of KIa.

10/10 experience, thanks to David!
David Gutierrez gave me a great experience buying my first new car! He was very patient and informative. I test drove 2 different cars. David also followed all CO-VID procedures which I was very happy about. I’m happy with my experience here. Thank you!
Bought mine a month ago!
Bought mine a month ago! definitely a huge upgrade. Kia really knocked it out the park with the k4! i have the gt-line in the white exterior! i’m obsessed. Get pricing point, i was stuck between this and the elantra i’m glad i choose this over the elantra, both are compact sedans but the kia definitely feels bigger and more tech and feels way more expensive than it is

Mercedes of ontario the best place to purchase !!
On November 25th I went to the Mercedes on Ontario, and was looking to buy an electric car around 7pm in the evening, I was looking at the EQB 350 when this very nice sales representative Abel Vargas helped us and was very nice and interactive explained to us what was good about the electric vehicles, at the end of the point of buying the EQB 350 the transaction at around 2am Black Friday after hours but I will like to mention excellent and outstanding sales person human being his name is fadi batarni I had a situation where I had to call him, a couple days after but was out of town but still answered right away, like always nice friendly and helpful manner, and I really appreciate the help and appreciate the huge help on purchasing my EQB 350 Thank you much guys I really like my car.
I have owned my K4 EX for about a month now.
I have owned my K4 EX for about a month now. It has been a great car! I think that the most fitting word for this car is value. You get A LOT for the money. I got my EX for under $25k out the door and for that I got a car that has a great design, awesome technology (wireless car play, huge touchscreen, updated safety features etc), fantastic fuel economy (40+ on the highway) and a very comfortable ride. This feels like a car that should cost at least $10k more than it does. I highly recommend this car.

Our 2022 EV-6 Wind just received it's 15,000 mile service
Our 2022 EV-6 Wind just received it's 15,000 mile service along with a couple of recall issues and a few updates. Chris Franklin, our service writer, went above and beyond our expectations by providing us with progress updates on our service. We were provided Lyft transportation home and our car got a complimentary wash too. GGK Service Dept. technician's did an outstanding job on our car and it was ready as promised. Chris took the time to explain everything that was done to our car and told us the results of the of the overall inspection.

5 stars from me..
Honestly the best experience you'll have buying a car. My salesman Antoine Fiveash (Tony) was awesome. Non stressful environment and friendly faces. Tony talked to me like a real person and not just another sale. I walked out happy with my new car I got for a killer deal!! I'll be back for my next car

Everytime I bring my vehicle in for service I am greeted and attended exceptionally well. I tend to ask for Yuri, as she has offered me great customer service. She goes above and beyond her line of work. She patiently hears my concerns and offers her expert advice with a smile. I highly recommend asking for Yuri and going to this Kia of Carson. Keep up the great work 👍.
