According to the 2010 GM Product Guide, the 2010 model year Pontiac Vibe is the only model from the doomed brand for 2010 and is, therefore, the last Pontiac. That's right, the last Pontiac is actually a Toyota.
The fact that the 2010 Pontiac Vibe is surviving until 2010 may have something to do with the join production deal GM has with Toyota to build the vehicle, along with its twin the Toyota Matrix, at the joint NUMMI production facility in Fremont, California. Every other vehicle will end at the 2009 MY with the exception of the fleet-only 2010 Pontiac G6, which may or may not become a strange collector's item for those willing to search the Alamo Rent-A-Car sales lot.
