I was thinking to do the same thing this morning but realised I had no minutes left
This tells me you should have no business trying to restore a Mustang however much you like it. You cannot afford it and it will ruin you.
Dream that dream by all means, but I think you have no chance of completing this project. 
I had no minutes because i used them, didn't run out of credit (Im on a contract, and used them on business calls before i left for work and cant re-add minutes until the contract rolls over again at the end of the month)

Everyone seems to be forgetting, i havent fully inspected the car yet, there could be near to no damage (Trusty pount shop blue sheet may have worked for god knows how many years

) or it could fall to pieces from rust at the touch of a finger, either way, If I was to get the car, it would be finished, whether it be slowly due to lack of funds or not, either way, money will be spent on it when the cash is there, sometimes I get a flow of cash in one week and others I wont get much to spend on things, it depends, so believe me or not when I say, If I do get the car, To the best quality possible, It will be restored.
