Some parts had the later revisions (slightly better reliability but basically the same), PCM2.1 had the phone button whereas most all '05's had PCM2.1 without the phone button (and came with Level A software which will need to be updated if not done already).

Fewer TSB's, but I'd say that only mattered during the first 40K miles. Functionally, and to what you can see and touch, they're the same. Reliability will be the same once you're beyond 60K miles. Same with cost of ownership.
