Mazda sent me the papers stating they have officially extended the engine warranty on the '04-'08 Renesis engines for 8 years (from date of purchase) and 100K miles! I knew about this a while ago but was not allowed to make posts about it (although I know other already had).
If you haven't got your paperwork yet, you should be getting it. I'm glad I got the car now as I know I wont put 65K more miles on it in the next 4 years!
I feel like the engine might go out around 75K miles though
