I bought mine from Canada (as if everyone didn't already know). I tried for a week to get a temp. registration/plate so I could drive it from there to CT (8 hour drive).
The people at the DMV said I needed the actual title to get a temporary plate. I explained to them that I can't have the title when I don't OWN the car yet. They expected Jim to send me the title when he was still driving it.
I got a photocopy of the title because one person said that would be fine. I brought it in but that wasn't good enough for the next person I saw.
I swear the DMV I went to was full of idiots.
I gave up and took a 14-hour bus trip one way, and drove the 8 hours back with Canadian plates. Crossing the border with Canadian plates wasn't even an issue surprisingly. Customs never even asked for proof that I bought the car.
