Remember the car is only contracted to last till 2012 right now, unless if was long term I could see a real change.
Actually, I don't think there is a
single published source that says this (2012). When I posted that the car should be good for a minimum of a couple more years, it was exactly that - a minimum. I am confident that the recent announcement was not a "bandaid" fix but a full-blown commitment to the platform for the foreseeable future. With as much hoopla as was given to the announcement it would seem only logical to continue to develop the Viper for the future.
That said, realize that supposedly-substantiated speculation on drastic changes in future generations only hurts current sales. Some folks like to say that they heard from a reliable source that XYZ is going to happen, which then has the very real potential to stall sales for the current car in such a very small market like the Viper. "Gee, if it is going to have rocket boosters and a 24" touch-screen DVD/stereo then I am going to just wait to buy." While that show of commitment from Chrysler/Dodge/Fiat was very strong, if current sales/interest plummet then all bets are off.
Personally, the only reason I would wait to buy a 2010 is if you like your model years to end in even numbers. Who knows, maybe they will have a price increase just to show how much they value the car now.
Get 'em while they are hot!
