I wouldn't fear a high mileage vehicle as long maintenance has been done on time and properly. Heck, we've seen well maintained 944's hit 300k mile range -- I'd expect the 968 to do the same or better.
I recently came across a 1992 175k mile cab in California -- the PO loved the car and took ridiculous amount of care on it. New tires and control arms in the past 1k miles. Clutch, timing belt, brake pads/rotors, and convertible top in the past 15k miles. The interior/exterior looks absolutely gorgeous -- even the engine bay is clean. There's even a sound system with a sub woofer, a capacitor, XM/ipod and extra sound proofing in the panels.
However, the problem with high mileage car is that the market is very thin -- if you buy one, be prepared to be married to it. A high mileage car has practically no resale opportunity because only an enthusiast who knows these car would even consider it. Frankly, if I didn't know the model, I would never buy a car with 150k+ miles and shy away from those with 100k+ miles.
Anyways, the PO for this car bought a Cayman and his wife wanted the 968 out. He found practically no buyers because of the mileage -- noone would touch it. It did eventually sell for $11k.
Now, in your budget range, I would also remain open-minded about 944S2. Granted, the S2 doesn't have the refined styling of the 968 (headlights, door handles, aero mirrors, taillights, spoiler, door panel, analog clock, thermometer, etc, etc....), lacks the Variocam (so 29hp less) and lacks the 6-speed transmission. But the benefits are the cost -- high mileage S2 are hitting sub $5k and mid-mileage S2 can be found in the $7-9k range.

Are you thing of Ted Wright's car in upstate NY? If so, that was a LSD car that's he bought from another Rennlister. I believe it eventually sold, though....
