If you got 1000 simoleons to spare, go to the hobby shop, and add the RC boat into your cart, add any other hobby object. Cancel that RC boat off the list, and buy. The game somehow glitches, and gives you 12000 in return for the RC boat that you were supposedly gonna buy.
I think that before anyone is misguided once more..I better make this thing clear. See, you actually buy that work skill increasing object, but you cancel off the RC boat from your list. This glitches, and the game adds >12000 money to your overall town value. For the dudes who thought it added 12000 simoleons, sorry to disappoint.
