hey, i live in chicago and the only dealership i have been to so far is Woodfield Hummer. Their sales staff is pretty nice and so are the techs, but they dont always fix everything they are told to, could be because i go in with whole lists, because its a bit far i wait till i have enough stuff going wrong.
Even though they dont always get everything rite the first time, they dont give me BS like what some of you guys are saying. They do get it rite the second time around.
So if your close you might wana check them out too. The service guy seems pretty reasonable, but he did give me a lilttle BS last time, i just laughed and he kinda got the point.
anyway good luck, and its gona get cold again so get ready for all kinds of noises.
