This is from Polk.
Basically half of 2010 sales of previous Pontiac owners have headed outside GM. I think I remember a while back some GM exec boasted that they would retain 80% or something like that.
My problem with these numbers is that they report 57,000 and some odd purchases for 2010. Well Pontiac sales numbers in previous years were around 150 to 200K. So what happened to those other 100 to 150 thousand yearly Pontiac purchasers? Was that fleet? Were the fleet numbers included in this survey? I'm curious as to what these numbers will do in 2011 and 2012. I am going to guess go down. Have a look at the numbers, it is an interesting read.
