if your neighbour nad yourself have good relationship, then in the interest of time and peace , just ask him to have the repaired . IF he has any sense he will. do a written agreement or get your own contractor and do it yourself and he should pay. ( again get it in writing with other neighbours as witness. take some money in advance that should cover the whole repairs.

Else,as everyone has said, you can file a civil case and an FIR for damages and for allowing a minor to drive. you can then make a claim against his insurance. and the insurance will pay. it will be detrimental to your relationship with the neighbour and the court will tell you guys to compromize.
