I have zero regrets purchasing my '13 Sierra Z71. I drove the others, hated them for one reason or another. I don't like their redesign. I bought mine for a used truck price since the dealership was unloading the '14's the day I bought it.
I'm not real happy with the demise of the Pontiac marque. My wife's '07 G6 has been an excellent little car. However, it is ridiculous to say "f*ck GM, since they were bailed out, and dropped Pontiac".. Chrysler was initially bailed out by the government in 1979, and later dropped Plymouth. I don't remember people being like this toward their products..
