Man that blows, sorry to hear that happened to you. It's sad when you do what you did and the guy is obviously a jerk. If you have all the info that you appear to have, he wouldn't be hard to find. I do it all the time, if you would like you may PM me any details and I will tell you if it's bogas or if any portion is accurate I can tell you we're he went to elementary school. Also I believe if you have an a agreement, like emails, PM', etc that still makes it a legal binding contract in which you would not necessarily take him to small claims court but even better file a lien on his car. I will do a little more research on the matter but I'm pretty sure you can.
