I still have my Viper and I am being more particular with it than ever, not knowing the future of it or parts, service, etc. I received the same letter from Nardelli promising warranty, etc. Considering everything recently, we bought my wife a Mustang GT vert. I really don't feel right buying a Fiat/Chrysler. I am old enough that I was around in the 70's to see what Fiat was then and I just can't stand the thought of them in control of Chrysler.
I would guess that's when aftermarket parts/companies will start creating more parts to take the place of stock. I just sold my Z06 and other than the motor block everything on it was aftermarket
