Hmmmm...I always liked the looks of the 911. I love the 300d. Personally...I'd probably keep the 300d and get the porshe, but I'd be going off emotion and not logic. How often do you get a chance to own a 911? We don't see those in my neck of the woods. If money was available I would go the "mothball" route and store one of the Mercs. Tough decision. I'm not helping am I?

Edit: Might want to change your sig if you get the gasser!
