Hi all

I am trying to plan a roadtrip from NYC to LA this summer, the tour will go on for about 6 weeks.
Is it wist to buy a car, or should i cound on renting one?
I have looked deeply at the Chrysler Sebring JX (i) convertible, any age, because its a nice roomy car (we are 4 persons)
Is there any place in NY i can rent that, and return it to LA?
