164,507 miles on my '93 SC400. Bought the car in September and have done nothing to engine/drivetrain other than change engine oil and tranny fluid. Runs great! Needs more exhaust noise! Plan to have timing belt, water pump and suspension bushings changed after Christmas. I Bought a used CD changer on ebay and will install it after I figure out/research how to better isolate from vibration. Besides CD changer, the only other things that need fixing are one burned out bulb on climate control display and flickering temperature gauge needle. One of the best things about these cars is that they are RARE (at least in Sacramento). I've only seen eight others in my area (5 SC300s and 3 SC400s).
