Hopefully they are car enthusiasts for a hobby, otherwise hard to see what they would be able to offer IMO. Looking at GMs or any other car manufacturers history, car guys (or gals) in upper positions make it all happen because of their passion for what they do, "CARS", whether engineering, marketing, etc., they started young, worked thier way up to the top, and understand the business in their field of expertise. Those old timers passion for automobiles in what ever way, made GM what it is, or was, Cole, Dontov, DeLorean, Earls, Knudsen, Wangers, etc. etc., same goes for any other company, Ford,Chrysler, and foriegn.
Lutz is to new at GM to give any opinion here, or where he'll place with the GM greats, hope the best, but giving top positions to anyone without well rounded experience (brought up through the ranks), or passion with the auto industry, it can not possibly be a good thing, hope it does'nt become a trend, if it is'nt already.
