For the 72-hour sale incentive, running form July 1 to July 6, GM offers 0 percent financing for up to 72 months on both 2009 and 2010 model year vehicles. Among the vehicles eligible for the incentive are Chevrolet Silverado and Suburban, GMC Sierra and Yukon XL, Pontiac Vibe, G3, G5, G6 and G8. The full list of offerings, conditions and eligible vehicles can be found here.
In addition, even if they are not included in the 72-hour sale, other vehicles will have reduced rate financing of 0 percent for up to 60 months for well-qualified buyers.
As for the Say Goodbye incentive, as part of the CARS scheme, it will offer consumers vouchers worth from $3,500 to $4,500 cash. GM warns that whether a vehicle qualifies for the CARS scheme depends on the type of vehicle the customer is trading in and the increase in EPA estimated combined fuel economy ratings resulting from the purchase of the new vehicle.

As you can see, at least as far as the 72-hour sale in concerned, GM has put on top of the list of vehicles eligible its soon to be discontinued Pontiac as well. Just to remind you, buying a Pontiac is not a "buy and say goodbye" deal, as the manufacturer will continue to produce parts and service the vehicles in the coming years.
