I purchased my new GLC on Dec 21st and so far so good. I have the 4Matic, panorama sunroof, lighting package, blind spot, premium package, heated seats and burmester sound system. I am really impressed with the lighting package, the led lights are amazing. Blind spot monitoring is great for highway driving. I wanted to get the interior package but that would have required ordering, but happy with the premium package. I thought about doing a special order and also adding the driver assistance package, but people I know that have those say they can be rather annoying. The only issue so far is the car takes a tap on the gas to get into gear, so backing out of the garage need to be a little careful. Got a decent price I believe seeing the car was only in the Chicago market for a few weeks so far.
