They are still going for sticker. A used one just sold at a large dealer for $2k off used, with 600 miles. Have to be patient on exotics. If you need to sell dealers are happy to take advantage.

To answer OP question a 2015 a year from now with 10k miles will probably be $220-$230 +/-. Spyder will be out and 2016 coupes will be out. 560/2 will have also been announced.
