If this has been answered before I couldn't find it. What papers do I need to provide to my tax preparer in order to claim the federal tax credit for buying my Roadster? I think my salesman probably told me, but I've forgotten, and I don't see any mention of it, or any federal-looking forms, in my Roadster folder. I could ask my advocate, but if I don't remember, maybe there are others out there who would appreciate the information also. Thanks.
