Due to her car not being available, my wife had to borrow my 07 RX8 (she does not like the work of shifting). She wound up breaking my right tail light. In looking online for a used replacement, I have some vendors saying 04 thru o8 are interchangeable and some saying it needs to be 06-07 specific. It seems the 04-05s are less expensive. Anyone know for sure?
Thanks for any advice.
