I've brought my Sonata and my wife's Forte here for service before and was very impressed. WiFi is decent speed, chairs are comfortable, but the techs were done so quick I didn't even need to settle in. Both cars are under warranty so I didn't pay a dime, but they found and fixed my problems super fast. I've worked with the Hyundai and Kia service advisors Justin and Drew on several occasions, and was always very happy.
Sales staff greeted me as I wandered, but didn't pressure me, and even left me alone totally I said I was just here for service. And I met another Ed that works here! We're rare creatures, and this guy seems pretty knowledgeable when I bugged him about the CX-5 that was on the showroom.
