After some amazing correspondence with their internet salesperson, Tina, I decided to give this place a shot over a closer Hyundai dealership. They offered a fair amount for the car we were interested in, so we went to give it a shot.
The salesperson, Unchu, was very friendly and helpful. We took the Kona for a test ride and began the negotiating process. I've done a ton of research on that car and the price and will say their initial offer was reasonable. I set the bar high for our trade, but they actually offered right around what kbb and truecar was predicting. It was lower than I wanted, but not an insult offer by any means.
In the end, a deal was not made, but I fully admit it's because I am far more picky than the normal customer. I will only buy a new car if the offer is simply too good to say no, but even as a super picky person, I will say that negotiating with them wasn't painful and their offer was fair.
If you are interested in Hyundais, I would definitely recommend popping in.
