Trailer Discount
If you select and sell the trailer on the parking lot, then go back once and click the buying icon, you can rebuild for 150 C what you just sold for 465 C (parking lot level 2), 1150 C (level 3), 2100 C (level 4), 3500 C (level 5), leaving you with up to 3350 C profit, and you can repeat it until you get bored! This works with some other building extensions as well, but the trailer is most profitable. Make sure not to de-select the option, as buying the extension for its regular price will be double the price as what you got for selling it. And make sure not to do this when you do not have at least 150 C to buy back the trailer!
