Sometime around 1995 Hiro Yamagata spent $20M in frame-off restorations of twentytwo Mercedes 220a cabriolets. He then painted each of the cars differently while maintaining a nature theme. The project was titled Earthly Paradise. The cars were displayed at the Hollywood Oscars in 1996. Eleven of the cars remain in the US while the other 11 were shipped back to a Japanese museum.
This example is currently for sale for $295,000. Arrangements to purchase can be made through Hemmings Daily.
