i have seen people who if they posses just a screwdriver kit become mechanic with a board that says something like,
Jai Ambe Servicing.
All type of servicing and repairs.
Scuter, Bikey, Motorcicle, Truk, All Car
TVS, Bajaj, Suzuki, Honda, Maruti, Hundai, Swift, 800
I know no one from this forum will ever go to such a place.
But then what i am trying to convey is outside people may not know renault engines better then the service center mechanics.
