There was a place in Los Angeles, a guy use to take C3 Corvette's and put Daytona bodies on them . Actually used real Ferrari parts i think. They used one in the first two seasons of Miami Vice. After that Ferrari apparently was upset about the car getting attention, and not being real. So they gave the production two new Black Testarossa's , which were then painted white ,because they photographed better at night.
On a side note Don Johnson was given a silver Testarossa by Ferrari in 1989, and he auctioned it at barrett jackson a couple years ago and got around 60-70K
