How can I get from LAX airport to Claremont?

I'm arriving around 11PM, so flyaway bus then metrolink is not an option. What is the cheapest alternative?

Not much alternative except have somebody come pick you up at the airport..

or you can just rent a car and drive yourself... you can rent a small compact size car real cheap for like $15 a day at the airport. Get the cheapest and very basic car. Drop it off the next day at their location near Claremont.
