I have a 2000 Boxter S with 200,000 as of a few days ago. I bought the car here locally for a song, knowing that 2nd gear was bad (6 speed). No real service history other that a clutch and flywheel a couple of years ago. I did a complete maintenance, 4 new tires, fixed some oil leaks, and replaced 2nd gear. I have put about 1000 miles on it with no problem. I have 3 other Porsches, but this one has become my run around town car. My next project is a muffler hack, the car is too quiet!
Keep having Fun!!
