Thinking about trading in my z06 on a Viper coupe. I mean these things can be had brand new for around 79k. I really want a yellow one with silver stripes. Thing is I was thinking of getting rid of the z06 in the spring possibly trading it in on a Murcielago. Is it a dumb move to trade it in for the Viper now as the z06 may/might hold its value much better? I really need a change of scenery.
