So I'm planning on moving to Windsor this summer [[will be working in downtown Detroit).

I'm a Canadian citizen, thats the main reason why.

Anyways, some questions I had

1. What do you suggest about cellphone, should I get U.S service with roaming, or vice versa?

2. Should I buy my car in the U.S or Canada, with regards to registration what would be better, especially since I will be crossing the tunnel daily? I presume I should buy car in Canada, since that will be my main residence?

Anything else I should look into?

I'm applying for Nexus card now...
