Bets should be placed when the actually production models are compared.
Pick the top 3 Review Companies ie: (Car and Driver, Top Gear and motor trend)
Place actual $$$ bets on the car that will be the "King of the Ring" < LOL @ that.
If judgments conflict pick the best of three.
You guys come up with the rest.
Make it interesting!
don't place bets too high, don't want no body gettin' shot out herre.
...or postpone until V-SPEC is released?
