So for sometime now, I observed that my car ( lexus 350) was consuming so much fuel and was also producing black smoke from the exhaust. I have been managing it like that for few weeks now because I haven't got the time to take it to my mechanic.

So yesterday, I decided to take it to my mechanic workshop for repair. The mechanic told that he will need to run some test to ascertain what could be the problem.

So I left the car with him at his workshop and left to be back later in the day. Just few hours afterwards, the mechanic called me to tell me that my car engine has knocked.

When I query him to find out how that could happen when my engine is sound and I just recently change my engine oil. To my surprise, after I left , he stated cruising around with my car, driving around town and engine knocked on a neighboring town due to damage bottom plate ; which was obviously cause by hitting the underneath of the car on a hard surface.

I have insisted that he get me my car sound the way I handed it over to him and he has been begging me since yesterday to have mercy on him as he doesn't have money. From the information I heard, getting a tokunbo engine can cost up to 400k .

This is really painful, don't really know what to do with the mechanic guy now.

Guys, have your mechanic ever damage your car while cruising around after you left the car with him. How did you handle it?
