Get rid of it, but don't think GM can just keep cutting its way to sales and profitability. GM should replace the iconic HUMMER brand with a clear, loud and public commitment to making not just a few $35,000 electric cars or $50,000 hybrid full size SUVs, but class leading small cars built here. The next Aveo / Wave that are to be built in the U.S. need to be no-compromise "Japan-Killer" cars (that are frequently updated, not left to rot for 7 or 8 years), bringing the small-car know how of Opel together with the low-cost, high impact design (take the "jewel like taillights", for example) of GM Daewoo, and finishing it with what was learned from designing the last Cobalt here.
No 20+ year-old Opel hand-me-down-to-Daewoo engines, but the best in cost effective small-engines that the Opel of today can offer.
GM can cut brands all day long, but they need much more than a car here or there to make up for all they are losing in sales and profitability. The focus now, at long last, needs to be on making profitable small cars, and making a lot of them -- something GM has put off for too long.
