These Mock-up 500c's with tree's in them are in NYC and part of New Yorks plan to plant a million tree's. This is weird but i think it's a "cool" idea. I wonder where the mock-up 500c's will go after they decide to remove them and plant the tree's where there suppose to be planted.

April 29, 2011 , New York - Fiat North America has contributed 12-foot pear trees that are temporarily planted in eight Fiat 500 cars through Sunday to participate in New York City Department of Parks & Recreation and New York Restoration Project's MillionTreesNYC effort. The cars line parts of Canal Street and the Avenue of the Americas. Once the cars are removed, the trees will have a permanent home.
Fiat's participation also is designed to mark the opening of its Fiat Gallery in the SoHo arts and fashion district, 18 Wooster St., and the unveiling of the Fiat 500 Cabrio, which occurred during the New York International Auto Show.
