Just a dumb guess. Starting in mid 2015, these cars will be showing up on the used market, and perhaps 25% cheaper than MSRP.
Why? Much like the first Z06's, they aren't for everyone. They are loud, have limited storage, and stiff clutches. People who thought they wanted one to drive will sell them.
You should have heard all the snivelers on forums:
"Something is wrong with my engine! It's making noises!"
"My cats must be bad, after 2 hours the trans tunnel is burning my leg!"
Same thing will happen.
