Don't get fooled by those online pay-to-join auctions. 80% of the time, seisure and goverment surplus auctions sell things at market value anyway. You only hear about the good deals. Sure, you have a better chance of finding a good deal, but something like that Viper are 1 in a thousand at best.
Oh, I would go with gunmetal or black stripes on that if any at all.
