It's terminal. Holes in the body, holes in the frame, everything on it's
last leg. I had to make a deal with the inspection station last year
promising not to take it back.
I have two rust free busses that will be letting this one live on, and the
car won't be junked but is becoming seasonal housing for WOOFers.
I would love to fix it if it's clutch hydraulics.
What's a good way to test it?
