Me and my pals are planning a road trip through the USA from April to June. We plan to start in Miami after 2 weeks in Cuba, head up to New York and then across to San Fran and LA. However, we desperately need advice as to whether this is even possible. We are all 18 years of age so I understand that renting a car would be impossible. We therefore plan to buy a second hand car or van, although we are unsure if it is possible to get car insurance as 18 year old and as a non US citizen. Would really appreciate any advice or links to websites that can offer us this.
