When will Honda stop building new 2006 Civic Sedans for the US market
to switch to 2007 model?

Some kind of semi-authoritative verifiable reference would be required
for an acceptable answer (a date alone is not something I can verify,
of course). A 30 day precision is acceptable, but a "fall 2006" or
"August-September" answer is not.

If it matters, I am especially interested in manual transmission
atomic blue Civic LX 2006 to be sold in Colorado.

Thank you.
