If you are talking about the "pops out of first gear" issue, that was with the early 2004s only.
The VIN you provided is from 2005 - so that issue is not a concern.

Iv'e owned two 6 speed Crossfires, never had the issue, but my cars were 2005 and 2007.

If there is some other issue with manuals, I've been here eleven years and I don't remember hearing about it.
