trying to find my biggest mistake

I'm far from the area, but a timeline of when you owned it and when you got rid of it might help. "When I was a teen". Although YOU know when that was, we have no clue. You've done nothing wrong. You're in the right place. Just give us all the information you can. Pictures will help. Not just one or two. ALL of them you have.
I wish I had some pictures, the only ones I could find were of the Demon 340 fender badge. I didn't want to post the person's name without his permission. As for time line, it was a long time ago, I'm 46 now and bought it for $200 when I was 12 or 14. When I sold the car, I don't remember the year. The post was made on Sept 6, 2015. The last post about it was Sept 11, 2015. I was hoping that maybe whoever bought it might see this. This pic was in the ad, hopefully it will be recognized. Thanks again.11802080_1127674847247257_640292502_n.jpg
