There is light at the end of the tunnel, and it is not a train.
Hi,
It is good to see that the information on this site has exposed you to the awful reality of buying a car in the US as a non-resident. Better forget that. Renting when you are both under 25 can be hoirrendously expensive. However, there is light at the end of the tunnel.
We have heard on this forum of folk who have used a consolidator, and had all sorts of extra charges waived. You might like to try that. One of our members from Brisbane used one with great success. This still will not allow you to rent in Canada and drop the car in the US. That in itself is simply not possible.
You may also like to try Adventures on wheels. Their rental minimum is 23. Although I have not used them, I have looked into them There have been positive reports about them on this forum. Be aware though, that they will not sell and buyback unless you hold a US driver's licence.
Further more, you might look into a local crowd. Another I have looked into but not used so far. (I plan to, though) You might like to try them out at home before you come over, just to see what it is like. Register on their site so you get the email updates. That should give you some idea as to how it all works.
My first two visits to the US all I did was relocate cars, driving some 24 cars and travelling some 45000 miles over the two trips - 13 weeks and 20 weeks.
What I would do, is stay in the place of my destination for multiple days, and then rent a car to go see the local sites, returning the car to the pickup point. (e.g. anything going to LV would give you access to most of the national parks in eastern CA, northern AZ and UT.
Good luck
