Viper or Challenger

I would buy the viper mainly on an investment point of view. You are more likely to get your 40 grand back out of the viper when u sell it.:thumbrig:

Exactly. It will be a LONG time before you'd be able to recoup your investment in a challenger. Even not looking at the investment side of it, vipers are just bad. Plus it'd be more fun to mod a viper.
