My car was hit while parking in the mall last week. The girl gladly left a note and the damage is est. $400 ( I took it to 3 shops for est). Now she called me saying she has a good friend that works for a body shop but he said he can do it on the side and charge significally less. I feel kinda bad if I tell no , and ask the $400 where who knows, this guy could charge under $200. What documents or proof or licenses, should I write down if I go thru this guy who does work on the side.
