My only suggestion would be patience. Two months is a very short amount of time to be looking -- you'll have many times that amount to kick yourself if you jump at a car that later proves to be a lemon. And many (if not most_ of the older 911s on the market are lemons. Rust, neglect and engine wear make compelling reasons to sell a car. And 911s are charismatic enough so that there are always eager idiots lining up to buy them. Take your time, let a few "perfect" examples slip through your fingers. There will always be more of them. Eventually, you'll find your automotive soul mate.
There are a lot of threads on this board like this one:

that show what you stand to lose if you get tricked into a car with chronic problems.
