ok. since my car came from Ohio and I’ve been through this already…
title needs to be signed and notarized with both parties present (guy I bought the car from “knew someone” and it was actually notarized before I signed it). NYS DMV wont even talk to you unless its notarized properly. Thats basically the only difference from NYS. I can’t remember for sure but I think the guy I bought from had to sign the registration over to me as well and I had to show that at the DMV too. But other than that, you still need a bill of sale (explain to the person selling that in NYS we have a thing called sales tax and its a common courtesy for the seller to write the buyer a receipt for tax purposes stating you bought the car for FAR less than you actually did). there might have been some extra fees to get the car titled in my name from out of state, but i cant remember exactly. but yeah, getting the title properly is the big thing.
