We’re not sure how the accountants at GM are coming up with their incentive deals, but some of the 0% financing offers from the company’s recent “72 Hour Sale” are back, through July 18. From the company’s own site, no Pontiacs or Saabs fall under the 0% plan, nor do most Chevrolets or Buicks. Check out Cars.com’s full list of incentives for GM and other brands here. The real surprise is that Cadillac and Hummer are the two brands continuing to offer 0% on all models and that they’re extending the offer through September 5.
