I've owned my 1992 Porsche 968 Cab for three years. Nothing has broken, I've only had to do the normal upkeep. Its build quality is much better than my Mercedes Coupe's! I installed a Promax chip for better torque. It really helps, especially in traffic with the AC on. I purchased it with about 42,000 miles, now it has about 53,000. Its radio was really bad and the top makes a little too much wind noise, but what a car! And yes, the girls do take notice!
The great build quality, looks, comfort (I'm 6'4"), and reliability. Porsche Club events are great.
