Heya, welcome to the board.
These are great cars and many ppl use them as DD's. They are pretty solid runners as long as you do proper up keep. The big ticket items are clutch & vario cam service. make sure you get a ppi done. I change my belts every 20K or so, but they can go for a lot longer. When shopping for parts, there are several sources to check to get the best deal. Paragonproducts, automotion, sunset porsche, performance products, etc.
Outside of cool color combos, the most coveted options are M030 Package, LSD, & Sport seats. If you are buying a coupe, i'd try and find a car with LSD. Sport seats are nice, but for a daily driver they would not make or break a deal for me. I also would not purchase an M030 car (i know most people would). But M030 is not a forgiving suspension. So if you are buying the car to DD, the standard suspension is much more compliant and doesnt bounce around/wander on uneven surfaces/over bumps nearly as much. As far as modifying the car, again i wouldnt pick up an M030 car as i would be swapping the suspension anyway. Paying a premium for an M030 equiped car is not worth it imo, unless of course you plan to track the car in stock class.
lastly, if your wife does not give you the ok. A more practical alternative to the 968 would be a 1995-1999 E36 M3. They offer very similiar performance and clean cars can be found in a similiar price range. They were also available as a Coupe, Sedan, or Convertible.
