Have a look for the AMX Centurion Card. It costs something like $1800 per year and you have to spend $250,000 or more to get an invite. It will get you top tier with rental car companies, Mid level on nearly every airline program and same goes for hotel programs.

My guess is that anybody who has one is going to buy a FC ticket, Rent a Jaguar, and Stay at the Plaza anyway.

Happy hunting.
