I fully agree that once I have gone thru everything have a 928 professional ( Chris Bauer) go over what I did. I raced a Lotus Cortina for 12 years and even my wife won a race in it. She is pretty good with a wrench as well. She rode a motorcycle for years.
If you buy a an older car like a 928 or a used race car etc, and you assume the previous owner
had it all sorted out, you are in for a real surprise. I would rather buy a car with the assumption that everything needs to be checked out.
