Hi! Welcome to
THE Saleen Forums @ SOEC.org and congratulation on your new purchase.
I have always enjoyed the the covers offered & produced by California Car Cover Company. -->
calcarcover.com
They have a wide selection of materials and I have easily replaced my abused covers under their warranty.
Call their Customer Service line and give them the details of your vehicle, they may be able to produce something for you that will fit perfectly.
Now you need a SOEC window decal.
Did you purchase the black 2011 convertible that was listed as a employee vehicle on eBay a few weeks ago? To my knowledge the hoods are composite.
