    I bought a 2017 toyota corolla two months ago and the car began to give me problems, I called to see if they verified it, they supposedly gave me an appointment and that they were going to send me a message with the address where I had to take the car but they never sent me anything. day of the appointment call and they did not answer! This is really frustrating for only 2 months with the car and it's already starting to have problems! Now I have to take it to the Toyota dealer and just to buy with such irresponsible people. I do not recommend this place at all!

    This place is awesome. Staff is very friendly and they have a great selection of cars. Gordo does a great job and helped me find my perfect car

    When shopping for EXACTLY what you want at a PRICE you want ask for EL GORDO. He goes above and beyond to make sure ALL your needs are met.

    See all

    (1.2k reviews)

    I recently purchased a Kia EV9 from Kia Garden Grove, and while there were some disappointing…read moreissues with the vehicle itself, the service and staff have been outstanding. After taking delivery, we discovered that the AC was not working, there was a significant dent in the fender that had been missed, and the vehicle was not as clean as I would have expected. Needless to say, that was frustrating and took away from the excitement of getting the car. That said, Kia Garden Grove has gone above and beyond to make things right. They provided a loaner vehicle, arranged to have the dent repaired, fixed the AC issue, and even delivered the EV9 back to me while picking up the loaner on the return trip. The staff has been professional, responsive, and genuinely helpful throughout the process. I am still bummed about the initial condition of the EV9, but I really appreciate how they handled the situation and stood behind the customer experience. Overall, amazing service and a great team. I would just hope the vehicle inspection and delivery prep process improves so future customers don't run into the same issues.

    ## Review for Kia of Garden Grove **Rating: **…read moreI strongly advise anyone looking for a vehicle to steer clear of Kia of Garden Grove. They are the textbook definition of "bait and switch" and "predatory dealer markups." I went in to look at a used **2024 Kia Sorento** listed online for **$27,696**. While the initial sales associate was pleasant, the experience soured the moment we sat down to talk numbers. Despite telling them upfront that I would pay the sticker price plus standard taxes and DMV fees--and absolutely no dealer add-ons--the finance manager presented an "out-the-door" price of **over $40,000**. They attempted to tack on nearly **$10,000 in markups and useless add-ons**. When I challenged this, the manager's "best offer" was to remove most items except for a **$1,500 LoJack fee**. This car already comes equipped with onboard tracking services; charging $1,500 for a redundant system is a blatant cash grab. When I refused to pay for something I didn't want or need, the manager became incredibly rude. I ended up walking out, and he continued to make unprofessional comments as I left the building. It is a complete waste of time to negotiate with people who don't respect your boundaries or your intelligence. If you want a transparent buying experience without the "market adjustment" games, take your business elsewhere--places like Carmax prove you don't have to deal with these ridiculous tactics. **Avoid this dealership at all costs.**
