Preowned mileage: How high is too high?
 

I'm looking into finding a preowned 993 or 996 (but who knows with a budget of around $30K!). In general, how many miles would you consider to be "too high" for miles on a 911? Do "issues" tend to rear it's head at a magic number, say around 100,000 (assuming good maintenance records)? I know there's a million variable and lemon factors, but just overall opinions appreciated.
