@mechanicsonwheels: During this pre-purchase inspection, a hard rev revealed dark smoke and heavy soot buildup. On a petrol engine, this is a clear sign of fueling issues, poor maintenance or internal engine wear. Always get a Pre-purchase inspection before you sign that logbook! #prepurchaseinspection #MechanicOnWheelsLtd #NairobiCars #UsedCarsKenya #carinspection
