As noted above by "Red-Ray," your ordering a carbon fiber part could hurt your order's progress. If the carbon fiber part you ordered was the dash trim piece, you could buy it from a dealer's part counter and get them to install it later or, if you are handy, install it yourself. There is a thread on this forum with more details about this option, here:
Im #5 of 5 at Jim McCay ford. If my order was easier for chevy to fill could they select mine before the 4 ahead of me?
I have considered canceling my order to go with Kerbeck but that seems kinda shady.
Dealerships only get paid when the car is sold (duh?), so what they are doing is going through their orders, calling their "orderers" in priority order, and asking, "would you be willing to remove your carbon fiber dash (your only constrained part), so we can move your order much faster." If that person doesn't want to give up the carbon fiber dash, they go the next, then, the next, till someone is willing to order the car without constrained parts. We have had folks on this forum give up their constrained part(s), get their order to immediately move forward, with a few then getting their car approximately 4-5 weeks after initial placement.
A good summation of the process. I had a convertible with the Z51 package ordered since July. When they actually starting giving out allocations, the Z51 was on constraint, and I stayed at status 1100, which is order entered, but not accepted. In October, my dealer e-mailed and asked if I would be willing to drop the Z51 package. since the car is for my wife, and she wanted the car sooner, rather than later, and didn't care about Z51, I dropped it. 3 days later I was at 2000, order accepted. 5 weeks later the car was built, and we pick it up at the museum this week. It's all about dealer allocation.
You mentioned you were 5 out of 5 at your dealer. If the rate on the CF interior stays at 15%, which I believe it's currently at, there is a chance your dealer will never get an allocation including the FAY interior. If it goes to,a higher rate, say 50%, then you will likely get your car (unless of course, numbers 1-4 at your dealer also want it.)
