I have a delivery date for my model 3 schedule soon at your facility. I live in NH and will want to transfer my registration from an existing 2011 Camry to the new Tesla. What procedure must be followed? Thanks in advance for your timely response.

What you need to do is get in touch with Tesla using there phone number or website: https://www.tesla.com/findus/location/service/dedham

If you take delivery in MA, you have to pay sales tax. You should consider home delivery.

I would suggest you speak to your insurance company

That's definitely something you'd do at the DMV.

I'd rather call them or check the DMV/RMV for that.
