You know what I'm gonna say...........14 year old cars??? Unless you are unemployed and have all the time in the world to tinker with them and love doing it, you will be working on machines with diminished returns and possibly lots of hidden headaches. I am doubtful that used car parts sold by individuals is very lucrative. I would think most customers would rather take a chance with a business that will offer some kind of warranty for the used part they are about to buy.
Live it up: There will be plenty of time to be old when you die.
