Oh believe me he would. Anything to avoid spending money. When he first bought me the car he had me driving around on 4 bald tyres for a month the tool.
If he bought you the car in the first place then he seems a pretty decent guy trying to help his son out. Sorry but if your dad can't/wont pay for repairs then there is always the option of trying to find temporary evening or weekend work to earn additional money, or consider selling some items.
