Maserati Quattroporte 2016 Q4 No paintwork or repairs Gearbox, engine, and body are in excellent condition, 6-cylinder, car mileage is 100,000 Full set of large rims The engine warning light has been on for about a year; I had it checked and they told me it's the serpentine belt, but I haven't replaced it yet. However, the engine has no issues and does not complain about anything
