We are 4 students from Norway who are going on a 3 month road trip coast-to-coast. We want a car wich we have planty off room in (SUV or VAN).

My question is: Is it cheaper to buy and sell or to rent one?

How much should we expect to pay for a car and how much is insurance?

We are planing to start in Salt Lake City and go west to SF and LA then cross in the south, and then north along the coast to NYC.

If you have any other tips, please don't hesitate to tell us :)
