This Independence Day might be the time for waving the red, white, and blue, but GM wants to nab some green, too. The automaker is extending its 0-percent financing sale, which it kicked off on June 24th as the "72-hour sale," until July 7th. The extension of the special financing offer allows dealers to capitalize on the increased floor traffic that GM's advertising onslaught generated. The sale and advertising frequency get people in the door, but many car buyers hem and haw, making it tough to close a deal in just a week's time. The extension gives salespeople a reason to ring up prospects and offer them the sweetest deal they can muster on a new General Motors vehicle. While we'd love to get a C6 Corvette for $20,000 off invoice and 0 percent terms on the loan, our blogging income likely supports a Certified Used vehicle instead. On that end, GM is also offering financing between 2.9 and 4.9 percent on a raft of used models like the Impala, Malibu, Envoy, G6, and Lacrosse. These are the most favorable terms you're likely to ever find, until someone starts desperately handing out -1% financing whereupon they pay you to take the car.
