Hi, most svx parts are still available, things like the sunroof deflector, rear speaker covers, cupholder, security module have been discontinued.
www.1stsubaruparts.com and
www.subaruparts.com have good prices, I get great prices from my local dealership, as I have established a relationship with them and Im the only local guy whos buying svx parts. Good Luck, what parts are you looking for.
