The car is worth circa 16,500 with a clean title, in the best condition. I would say around 12k would have to be your asking, even though the car is structurally sound, yet the branded title unfortunately brings the value down.
I'd say try autotrader.com and craigslist. You'd probably get some bites there. Given you have the before an after pics, you might even get very close to what you're asking for.
