I picked up and old 78 tbird for 1300 bucks with 106k on the clock. Changed the oil immediately and slowly worked on it for about a year. Only time it was ran was to move it in and out of my garage or to revv it up to show friends. Also didn't have an air filter on it at any point in a dirty garage. Finally have it in good road worthy condition (lots of electrical problems from water damage) Currently have about 1k on the oil and will post a follow up analysis when I receive it.
