Hello,
You are not obligated to inform the buyer if it was in a accident unless the vehicle was totaled and you have a salvaged title. Since this occurred before you even owned the vehicle there is little he can do to hold you liable since this was sold as is and it is still in good running condition.
The buyer is obligated to do any car checks or have the car inspected prior to purchasing it, not you. As long as the vehicle is in running order and can pass inspection he has no recourse.
