I have close to 60,000 on mine with a SC added at about 45,000.
The only problem was the latch broke on the passenger driver side seat.
Changed the plugs, have the old type and had one break during SC install. It was easy to fix.
Some guys have their 197 above 150,000 with minimum problems.
Not like my Honda where the gaskets leaked, throttle body always sticking, then the AC going out. That's my history with a Japanese car.
