My wife and Mother in law are at an auction right now where this is going to get auctioned

I hate being broke!!! My MIL loves steam engines and trains in general and apparently there is A LOT of train stuff at the auction. Basically my wife is there to hold all the stuff she buys. I told my wife I could do $100 for the Caddy. Stupid money!!! There is also a cannon but I know myself and I should not have that. I would totally try to shoot it.
