GM's heavy marketing push and 60-day, money-back guarantee program haven't exactly shot sales through the roof; whether despite this or because of this, GM Vice Chairman Bob Lutz has publicly announced that the company may extend the offer.

According to Automotive News, Lutz used some of his time during an interview with CNBC to say of the money-back deal: "It's possibly renewable. We'll see what kind of experience we have." He also said he expects "way under 1 percent" of consumers to actually drive their Cadillac, Chevrolet, GMC or Buick vehicles back onto the lot.

Granted, the program -- currently slated to close at the end of November -- hasn't actually bumped sales; at best, it's expanded the pool of consumers who would consider a GM model. But given that Toyota has surpassed GM as world's largest automaker and that GM recently spent a stint in the bankruptcy clink, I suppose every little bit helps -- even if it's just in the theoretical-purchases realm.

(Editor's note: Fun quote from the article: "Lutz said GM dealers are low on inventory of better-selling vehicles but have 'plenty of inventory' of full-sized sport-utility vehicles and pickup trucks." Heh. No surprise there -- as we know, Chrysler has the same problem.)
