The smartly-dressed fellow in the photo above is Uwe Ellinghaus, and he's Cadillac's chief global marketing officer. And he's here to answer all your questions.
Uwe is one of the guys who's working to make GM's luxury brand compete on the global stage more than it has in the past. Before coming to Cadillac, he worked in a number of marketing positions at BMW, and was their chief marketing officer responsible for BMW's brand strategy and marketing services for MINI and Rolls-Royce.
Uwe will be around for the next hour or so. Ask away!
Update 2:55 p.m. Uwe had to split, but he thanks you all for your great questions. I think this went really well. We'll have to have him back sometime!
