Oh well my Their job usually involves the repair of a specific part or the replacement of one or more car parts usually. 
yeah how was your day?
My day was great, Its so busy and all with fixing cars which is rewarding because it also pays well. 
are you interesting doing work on cars 
I sure am, I often have to quote prices for my customers before doing any work or after partial disassembly for inspection.

Thank you, Most people dont realize that basic vehicle maintenance is an important part of a mechanic's work in many countries, while in many other countries the customers are only consulted when a vehicle is already showing signs of malfunction.
