The second rebuild was done 1400 miles ago. I am very concerned about how the car was maintained, I'll talk to the owner tommorrow and ask to see all the documentation
concerning waranties and extensions due to recalls. If the price is right and the owner can prove the car has been serviced at the required intervals .... I'll consider buying it. I would send an oil sample to Blackstone Labs
but the pan was just dropped recently so I don't think I could learn anything from a lab report.
