Auto repair has to be done on vehicles whether the owner is a millionaire or in the group that is considered in poverty. Sometimes the low income families are able to get help fixing their vehicle though. There are special programs that can assist them if they do not have a vehicle that can be driven to work.
Most of these programs will require a quote letting them know how much this will cost before a decision is made regarding this. This ensures that the bill will not be higher than the allowed amount. Sometimes proof of having a job is also required.
