Why would they let a car sit on their showroom floor for over 2 years? It makes no sense for them to leave money ******* in a car for that long. If they have had it listed for $100k for a year, it's probably time to rip the bandaid off.
There's been plenty of dealers who have sold Vipers at a loss. It's a reality when they ordered too many floor models for a car that didn't sell well.
I've already found a new 2014 GTS at $85k, but it wasn't optioned to my liking. It's no longer listed, so I assume it sold. I am confident they can be had in the mid-low $80k's with a little patience. I don't foresee leftover 2-3 year old models selling at $100k. This is only my opinion.
