I believe $13000.00 is a good starting point.
For a transmission to be so clean, I believe it was full of oil before it was power washed, otherwise it wouldn't be so clean and shiny. This engine/transmission is probably leaking oil somewhere.
This vehicle is a high mileage car, I believe.
Over all, this seems to be a good vehicle if you have $6000.00 / $8000.00 set aside for restoration.
