MIAMI (AP) — More than 50 high-end vehicles and watercraft are being auctioned in South Florida by the U.S. Marshals after they were seized in a pill mill takedown.

The auction Thursday in Opa-Locka includes souped-up hot rods such as a 1930 Ford, a 1969 Camaro and a 1966 Corvette. Also being sold are a 1999 Lamborghini Diablo, a 2009 Mercedes-Benz SLR McLaren and several personal watercraft.

They were all seized in a 2011 Drug Enforcement Administration operation involving seven pain clinics in Miami-Dade and Broward counties. The operators were charged with illegally dispensing hundreds of thousands of powerful prescription drugs such as oxycodone. Most have since pleaded guilty to criminal charges.

Proceeds from the auction go a Justice Department fund used to compensate victims, supplement law enforcement and support community programs.
