My understanding was only 2004 and 2005. If you do a search on the forums under "E85" someone said that you can tell by looking inside your fuel cover and on the serial number of your vehicle. I think if the 8th digit is a "Z" or something like that it is a FFV. Mine is a 2005 and it shows on the inside fuel cover that it can accept Ethanol based fuels. This would probably be your best indicator. Hope that helps.
