Fix My Friends Truck For His 18th Birthday

My friends 18th birthday is coming up in September, and me and all of his friends are trying to fix his truck up. He’s a really good guy and he would do anything for all of us he has been down on his luck financially even though he has worked a full time job since he was 14 years old and has gone to school at the same time. Me and all of his friends have got together and decided to do this for a person that doesn’t think of himself but always thinks of us and people in need. So any help would be greatly appreciated.
