GM's struggling brands: Room for hope

Buick has the basics of a brand turnaround in place. It has some good products. The Enclave SUV and Lucerne full-size sedan have earned critical acclaim and the Enclave, at least, has been selling as fast as GM can make it.

Buick's market share is still small - just under 1% so far this year - and shinking.

To find broader appeal - and to get its sedans selling - Buick needs to dig out from under its image as an "old man's car" says J.D. Power's Tom Libby.

With recent quality and reliability gains, Buick may have something to work with. But that "old man" is a tough image to shake.
