Mafia Wars

Is there anything more addicting that Mafia Wars on Facebook?  I'm finally up in the upper levels and excited about unlocking more tools on level 99.  One of the big problems is that you can't spend the cash you make on anything... seriously - how many town cars do you really need?  The other thing is the requirement to have a certain number of mafia members to get certain loot.  I understand the game's sponsors are trying to get more user and monetize the application, but wouldn't it be great if I could spend the money to buy mafia members... sounds like a fraternity, eh?
