I'm not sure about leasing through DCFS but I was offered a lease option when I picked up my Crossfire, but I decided to buy.

Your dealer should have the ability to perform a inter-dealer stock search. Mine did that for me and we found that most of the 6-speeds were in Florida which seems to jibe with what I've seen here in the Forum.

If you'd like, PM me and I'll give you somebody to call and he'll do a nationwide search for you. He's a good friend at the dealership.
