I ended up getting this CNA warranty too.
My dealer offered both CNA & VW.
The coverage on the CNA had slightly higher amounts and were not exclusive to VW garages. Though almost all work is going to be done there. I was leaning to the VW Platinum but with the CNA they include a Dealer Maintance Club - lifetime oil changes (2 per year), 10% off parts and their was a few minor other "Dealer Club" features so I went that route.
Joe assured me that it was as good coverage as VW. I guess Volvo factory warranty is CNA - funny thing he said if I go to Volvo my name will be in their computer system.
If anyone is interested this is the guys info:
Joe Cabera at Mitchell VW in Connecticut his email

He told me that he would beat the regular rates by a little over 10% better if you have a CPO. I've been talking with him the last few days and he's a good guy.
