My Selling Dealer, Orlando Hyundai, also does not have marble floors, granite countertops or free lattes. Also do not have those expensive large leather chairs. HOWEVER the four Service Writers all greet me by name, one even brought me back a souviner when he returned from vacation. The one Genesis trained technician knows what he is doing. (Example, when he did the P06 update, he got it done is less than 4 hours vice the day or two other dealers took that I read about on this site). They will also give me a loaner, even if car is only there for a few hours.
The dealer that did an AirBag TSB, Chapman Hyundai on Bell Road, Phoenix, did the update quick and both the Tech and the Service Writer seemed to know what they were talking about. In addition, although the TSB only took about ten minutes, they cleaned my car FREE, inside and out. Took longer to clean the car than it took to do the TSB.
My closest dealer, Jenkins Hyundai in Leesburg FL has a policy that I can't talk with the technician, can't go in the service area, can't peek into the service area, and will not give me a loaner unless my car has to stay there overnight. I gave them a chance when I wanted the P06 update done, but the Service Manager informed me about their policy, so looks like I don't go there for any service. (Their Parts guy is great though, and gives me a price break on various accessories).
Although I never had my Genesis serviced in Roswell NM, I have visited them, and Roswell Hyundai has their Service and Parts Departments located within Roswell Toyota. Strange. Also can't go into Service Department, but "you can look through the glass window into the Service Department" and if you are lucky, you may see your car close enough to see what they are doing.
Don't know what their policy is on loaners.
Fucillo Hyundai in Greece NY (Rochester) also has a viewing area where you can look though the window to see what is going on with your car, but again, you can't go into the Service area. Again, don't know what their policy is on loaners.
