I found this article on one of our Marine forums.
This guy shares the same interest as I do, but had to have the best of both worlds

The VW Bug Artificial Reef
This week's winner of the "Ain't that Cool" award goes to this artificial reef sculpted in the form of a classic Volkswagen Beetle. The eight ton concrete replica was created by English artist Jason deCaires Taylor for his Cancun Underwater Museum (Mexico). Read on for more details about this exhibit and the Underwater Museum.
The life-sized VW Bug replica (with a sculpture of a person on the windshield) is the latest addition to the Cancun Underwater Museum. Engineers carefully lowered the 16,000lb showpiece 26 feet below the waves of Manchones Reef, Mexico. The exhibit was specifically designed to serve as an artificial reef for fish, crustaceans, and the recruitment of hard and soft corals alike.
Included in attacehd photos is a diagram of the design elements, as well as a photo of the concrete vehicle being slowly sunk into position onto the sandy reef floor.
Before its even in place, fish are already clamoring to swim in their new playground!
