Tomk17, it won't fit!
You want the Porsche Tequipment cover # 987 044 000 00. I have one and it fits great. I am using it for indoor winter storage. I got it from"Santa" last Christmas.
I think it cost about $280. I bought from either
www.sunsetporsche.com or
www.suncoastporsche.com. Call both to see who has the best price and shipping charges.
When you call them, ask about the front and rear trunk liners. They are also very nice. Better to buy everthing together to "save" a little on your shipping charges.
