I want to tell you, things happen to me with this mechanic.
Twice i brang my car to him and he repaired it for a good price.
The third time he told me an engine rebuilt is needed, he told me the price and I said do it.
 (estimated time 5 days)
It took two month's to get my car back, i couldn't imagine, every week something new or other problems.
Finally I got my car after 2 month's from his garage, but it was smoking like hell,  i drove back to him again new problems... I got the car back 4 weeks later...unbelievable!!!
In the end I went to another garage, and they told me Luciano (or whoever) put the wrong spare parts into my car. Instead of a Mercedes C-Class injector the drilled a bigger whole into the engine head and installed a A-Class injector.
The only way to repair that, is to buy a new engine head. Also he was getting spare parts from my car and installed older/damaged parts. Nice to know is also that not he is repairing the car, there is a another garage close to the new NATO HQ, which he brings the car to. I saw this, because I needed some paperwork out of my cas and also my Italian neighbour told me that.
I just want to inform you, be carefully if you want to have your car repaired with a mechanic like him!!!
