Need cheapest car rental option for US roadtrip?

next trip, go with the cheapest http://www.airportrentalcars.com/?m=1

As everyone else has mentioned there are additional taxes involved when the renter is not an American citizen and is under 25. Your best try at hitting a great offer for your car rental is to back a great offer. You can save money by: * Renting over a weekend * NOT renting from the airport location * NOT renting one way * Renting well before your pick-up date Since you'll be flying from Australia, why don't you look at offers where your flight tickets are clubbed with your rental? Hertz has such offers aplenty, may be you can have a look at these. https://www.hertz.com.au/rentacar/specialoffers/index.jsp?targetPage=specialOffersPerCategoryView.jsp&Category=P Also, google car relocations and try to find someone who is looking at the same route as yours and same time interval. It's a pretty meagre chance but it's worth the try and costs very, very less.

and if you are solo why not go bus,train or fly? if you go greyhound bus you can sight see. you can go anytime after the date on the ticket. while you are are on the bus you can get off at a stop, look around or stay a day or 2 in town and then get back on the bus later. i've done it on the bus don't don't know if you can do it on amtrak. heck, you could buy one of the 30 day or 60 day passes. or if you are with several people buy bus tickets for everyone one way to lax and rent a car for several days several times along the way to lax. rent a car in vegas and return it rent a car in denver and return it

The driver will be over 25 and with a US license. Surely if you're hiring from a company that has car offices all over the country then it shouldn't matter. (I'm the same person who posted the question).
