It runs that is good very good but the motor is the easiest and can be one of the smallest expenses. Check the frame is it straight. Is it rusty. If the frame is bent and rusted then you have alot of work that would destroy any budget. Same with the body. Rust will be found but is it surface rust. Tap it if your fingers goes through it then replacement is neccesary. Again expense and time that will destroy budgets. These are the areas to look at. In my opinion at least. It sounds though like it would be a good project. Also is it a farm truck or a city truck. Farm trucks will be beat up more body wise but most farmers will have there pickups purring like a kitten.
