So a former colleague used to do that in Lahore, and this has its appeal, I mean I really do not want to spend my days visiting workshops.
So you see, time is money, say for 8 hours of mechanical work, this costs me like 2000-3000 extra for the home service, and maybe , hopefully not say 10-15K extra charges because of thug possibility sometimes its just not that much of a cost compared to the time I can put into my own work.
