Can someone give help for a small claims case?

my car got hit in a parking lot by a co-worker and we both have PLPD in Michigan. He was clearly at fault and got the ticket. i will only be able to get $500 from his insurance even though my repairs will cost about $1300-$1400. He wont give me any money so i am forced to go to small claims. i have not yet told him or scheduled a court date yet. i have gotten 2 estimates and have not contacted his insurance company yet. This accident happened mon june 27 and i would greatly appreciate any advice or help from anyone with experience. Is there something i am missing out on that would ruin my chances of winning the case? What if he doesn't show up for the court date? help please.
