As a police officer who investigated thousands of hit and run crashes in 15 years, you will be lucky if you ever see the car again. Even if you do, since you didn't have a good description initially, there is little you can do. You can try and go to the body shops,but in my area there are hundreds and that doesn't count the guys who do stuff in their garages on their own. Plus, do you think the body shops will likely give up someone who is paying for someone who isn't? Also, I can tell you with high certainty, that the driver was probably, 1) suspended, 2) intoxicated and 3) had no insurance.
ThankGod you are basically OK. You will be sore in the morning once the adrenalin dumps is gone. Take some ibuprofen or tylenol and go to bed.
