I've been looking for a xfr for about 6 months now .I used to have a n.a 2011 5.0 and loved it but wanted to get an xfr .Had some of the worst luck in my car shopping endeavor..But I guess it all worked out. 2012 One owner 46k miles .Tons of maintenance records . California car .Got it at carvana which I was shocked because I looked there before and their prices were 5 to 10 k more than anywhere else I looked .Got this one for about 6k under blue book .So just wanted to introduce myself and looking forward to modding the car .Gonna start out with some visual mods ..Thinking about making the wheels a little darker grey,blacking out the window trim. Painting the calipers and window tint for now ,I'm sure I'll find some other stuff to do.

 

 

Nice catch

 

One simple, easy and cheap but very effective mod you can do straight away, which I did on my old XFR (2010 Kyanite), is to pick out the lettering on the hood vents ("supercharged") and on the side vents ("Jaguar") in some contrasting paint. I used silver paint on the hood vents which looked great against the Kyanite but with a Silver car you would be better off using something darker, probably best to go with black or maybe red.
I used left over caliper paint (sprayed into the lid of the can to make a little puddle) which worked great and it never faded or degraded one iota.
The method I used is easy:
1. Thoroughly clean the letters, I used meths and a microfibre cloth.
2. Using a medium size artists brush paint the letters, as thickly as you can but without letting the paint run.
3. Don't worry about making a mess outside of the letters, see step 4.
4. Allow 20 or 30 minutes for the paint to dry/set then gently wipe/rub off the excess paint with a rag dipped in turps. Even better, if you have a paint touch-up kit such as Chipex, use their "blending solution" and little rubber/foam block and wiping cloth, this method is easier/better/faster than using turps.
5. Apply another coat of paint, rinse and repeat.
6. Two coats usually does the trick but you might like to apply three coats.

 

I actually see they make carbon fiber replacements which I was considering..but I like your idea also
