Some day I'm going to make a meeting and actually become a real life member of this club... The darn meetings just happen to fall on the same nights as fire training. Doh!
Anyways, for fire department extrication training we call wrecking yards and they will bring us cars to cut up for the price of the tow back and forth. It might be worth asking one or two if they would be willing to do something similar for the how to recover a flop training... Nothing beats real experience. If you go this route, ask if they'll empty the fluids before they bring it.
