Hey,
I'm a German boy, and I'd like to do a RoadTrip in the USA after finishing school next year.
Me and a friend of mine had the idea to make a road trip, roughly along the whole west coast.

The problem is our age, we will be 19 years old next summer, so we can't do autodriveaway and can't rent a car.

Do You see any possibilities for us to do the road trip?

What about buying a car in the US, can we easily do that?

Or can we ask another person to register the car on his name and sell it without that person?

Or does it work to buy a car in Canada and sell it in the US?

I'm very thankful for Your answers, they would really help me!
For what price can we buy a car that works well?
After the RoadTrip we will fly to South America and go backpacking there for half a year.

I'm looking forward to get some helpful advice!

Jannis
