I think that many good points have been made here...especially by JonB(surprise, surprise !!!).
However,bigdeep1, you stated your plan as "I plan on getting a Viper in the next 3 years". SORRY, but you are already late... if you do not act NOW, all of the other speculator-investor-collectors are/will be well ahead of you!!!
In collecting...be it art, cars, guns, or whatever...the key is to know the product, the market, the history of same, have finances READY(a REAL collector is always broke...but still finds a way)and MOVE immediately as the opportunity presents itself.
SOLUTION: Call Bill Pemberton at Woodhouse NOW and try to lock in one of his already ordered 2010 UNIQUE Vipers.
