selling a car without registering

I had backordered a car few months back which is supposed to come in this week or next. At this point I cannot change the color or options, so I will only get what I ordered. Since I’m in no hurry to get the car, I can either let the dealer know that I don’t want it or I can make some money out of this deal and sell it to someone with a markup since there is a high demand for it right now.

I wanted to know if there is a way around to not having to register the car under my name before selling it. If anyone has any experience doing this (in US), please let me know.

Thanks.
