			I recently bought a 2007 987 without a wind deflector.  I also wanted the wind deflector.  I don't know what the invoice price is on the deflector, but you may get the dealer to add it for his cost.  They will probably want to charge you a couple hundred for labor as well.
 I added the hardtop this way.  It cost me $2000 plus $515 labor.
 
 I just ordered the wind deflector kit (from sunset porsche) for ~$400 delivered.  The kit includes the mesh screens, the glass, the clips, and rivets.  After it arrives, I plan to install it myself.  If your interested, I'll let you know how it goes.
