"From the other reviews, it seems like people have bad experiences with Car Pros Kia in Huntington Beach, but wanted to share about my positive experience in getting my new 2012 Kia Optima SX.
My situation was a bit different because I had been negotiating online through email with many different dealerships, and I had actually already decided to go with a car from another dealership. However, I was only in the area for a couple of days and the other dealership couldn't have an actual vehicle for me until a couple days later. So the day I got into the area, I called up Car Pros Kia. Mario was my sales manager and he told me he would match the other dealerships price and I could get the vehicle that day if I came in. So I went on over to the dealership, and about 2.5 hours later, I drove out with a brand new Kia Optima SX. He matched the price for me, and because the car at the moment didn't have a full tank of gas, he told me to come back in a few days after I use up the gas, to get another full tank of gas for free--which he honored, which is awesome.
Not sure what the experience would be like if I just went in without a quote already from another dealer, but my experience with Mario at Car Pros Kia was very good. They will try to use typical "sales tactics" on you, but you have to understand and know how to work around that."
