Had a bad experience buying a 2009 Hyundai Genesis from them! They advertise their cars as Certified pre-pwned but in small print, they say it is "pre-certified". I talked to John and he informed me it was "pre-certified" which basically means nothing. My car had 23K miles when I bought it. I flew in from OKC to Chicago and when I got there, they informed me that it would cost an extra $2700 to certify the car up to 100K. For a "pre-certified" car, the fuel pump went out as soon as I drove back to OKC. before I flew out there, I had an agreement that I would drive away with the title, as long as I bring the check. When I got there, they inform me, that they can only mail me the title. This process took a week and a half with them informing me that the title had already been sent out. A week later, I get a phone call to verify my address so they could send me the title!. FOr someone who flew all the way from OKC to do business with them, they wouldn't even offer me a cup of water, but rather pointed me to the vending machines when I asked for some. Really disappointed in their customer service.
