Buying a car as non resident.
My wife and I are planning to drive from the East coast to California late next year, we would like to buy a car and take our time driving. The plan is to buy a car after we have crossed the border from Canada so any state down to New Jersey would probably be ok. As you can imagine having never done anything like this before I have many questions, such as how as a non resident would I buy/ insure a vehicle? what actually purchasing a vehicle entails in any given State? What are the pitfalls/ things to look out for. I'm sure I will have many more questions but for now these will do. I look forward to the answers and tips any of you feel I may need to know. T.I.A.
Good luck but it is not easy to get that visa for tourism only.
On what grounds do you think you would be granted a B1/B2 visa? You might like to check this thread. The timing as far as when the clock starts ticking is still the same. If you transit through the US on your way to Canada, then the clock will be ticking all the time while you are in Canada.
We can't really help with advice here, until, as Michael asked, you post your complete plans for either 90 or 180 days.
Even with a six month visa, I would still think that your final costs would be as much, if not more than renting a vehicle. You certainly will have much more peace of mind knowing that any accident/breakdown is covered by the rental company, and you'll be on your way a.s.a.p. Renting will also get you a near new vehicle, instead of buying another persons cast off; and you will have it on the day you book it, without having to wait possibly weeks for the paper work to be finalised.
If you go through one of the consolidators, like carrental.com, there are really good deals to be had. Further ways of saving money with a rental, would be to do a loop trip around the country, rather than a coast to coast trip with a possible sizeable one way drop fee. You have plenty of time!
