OMG, how the heck do I in crease my profit margin to $20,000.
It's the only problem I have ....I have a 100% of everything else and because of this, my Detailed Performance Rating is is like 900 to 920 and I don't know how to get it to go any higher!
Please help me...

Step 1: Use fewer bangs (exactly three fewer, as it turns out) in your topic titles.
Step 2: Sell all vehicles that aren't making the required profit.
Step 3: Install TTDPatch, and turn on the appropriate switches.
