I know the rx-8 is too new to be in the kelly blue book... so while i was with my wife at a car dealership... I thought i'd have them appraise my rx-8. I told them it has the GT package and they told me that they actually had a couple of rx-8 trade-ins and that the most that they bought it for was like 20k-23k ... hmmm... that made me a bit worried there.
