I realize this is a late post on this issue, but:

I just purchased an '04 with 30,500 miles... I am the second owner... The warranty is tranferable to the second to the second owner of the car; it says this in the owners manual... My transfer was $162 including sales tax.

'04's came with the 7/70 powertrain and 36 Month/36,000 basic... The '05's did not, only 36 Months/36,000 miles... Hmmm? Do you think they are trying to avoid paying for these differentials?

I will be listening very closely to mine...

However, if you have an '04 you should have the 7/70...
