I am looking at purchasing a 79 mustang turbo for $1500. It has 80,000 miles but the trans has already been replaced by the owner. I didn't drive it around but I was checking the clutch on it when I saw it, it was the stiffest clutch I have ever felt and the stick was rough. I'm concerned about buying it because very soon I could be having to throw another $500+ in it soon. The 4 cyl turbos are already known to be unreliable, and I knew it has had its cams replaced among other things. Is this a risk I shouldn't get into or take the chance? If I do, any prevention ideas? I'll probaly have to take the trans out to check out what was done down there, but by that time I'll be out $1500, for me being a college student that is a lot. Any thoughts? I'm looking for any kind of help since I'm gonna probaly decide by this Saturday and I wonder if anyone has had experience with something like this. Thanks in advance guys.
