This is a really nice car and will make someone really happy. The 03-04 are my favorite 986's.
The first thing I would do as a buyer is replace the IMS (just did it on my 03 Carrera) but that's just me and it would not stop me from considering this car.
You may want to post the car to something better then Craigslist as it seems to draw mainly bottom feeders looking for a killer deal. Try PCA's website, Excellence or Cargurus. I sold my Boxster in a matter of days for what I consider top dollar with multiple serious buyers vying for the car. Speaking of the IMS, mine being done and having some miles on it since the work was completed was a big plus. At this point virtually everyone is in the know about the IMS even those new to Porsche (I had a 18 year female buyer asking me about it).
