My friend an old time mechanic has a ramshackle garage in a delapicated dysfunctional Coop Store., He is 75 yrs yonge and keeps the local Inhabitants jalopies chugging including mine. All older model cars I might add. He is an excellent mechanic but not a technician that is required for new cars. He uses a hand held computer to diagnose problems and order parts to make repairs but stays away from the electronics of new cars. He is a dinorsor mechanic with labour costs a fraction of dealerships.
