Hey Guy, I'm driving a 13 years young 940Turbo. This car refused to fail so I have no choice but continue to keep it. Honestly, from my memory, all wear and tear parts had gone through one round of change including the tranny. The major parts that are left untouch (1) engine - a bit of sludge noted and now undergoing auto rx treatment as recommended by experts (2) the alternator is still original bosch and the oxygen sensor never has been changed and never failed emission test. Mileage 150,000 miles and mechanics advised not to touch unnecessary. Just also to mention the turbo Garrett unit is still original and has never been serviced. What should I do next since I have a bit of time lately to spend time upkeeping this brick. By the way, cracks are seen on the leather seat that needs to be fixed.
