NPP cost me almost $15K.
Was shopping for a nice used 2010 or 2011 Camaro 2SS with a 6 speed. Max I wanted to spend was $25K. Checking out a used White/Red-Stripe at my local dealership and noticed a blue 1LE they had in the lot. Sales guy fired it up and put his foot into it. I went weak in the knees and two days later I was back trying to order up my '14 1LE with NPP.
I have to wait till Feb to get mine ordered, but that's how NPP cost me almost $15K.
