WRX STI Sedan 2011 - rear boot spoiler???
 

Purchasing a nearly new WRX STI 2011 saloon - the one i am buying doesn't have the rear boot spoiler but a few on the web do.

Is there an official subaru rear boot spoiler to buy or is it a after market product. If so where or who are the best to paint and fit a rear spoiler and what is the cost?

thanks
