If rely on myself and friends to do something this involved, and something goes wrong . . . ? I can't afford to do it twice? Neither the friendships, time, money, or even having the vehicle tied up again?
My friends own the shops I take it to. How did they get to be friends? We were each others customers. The old, stop in with coffee and doughnuts when you haven't needed their services for a while, and being retired, they don't use mine still work.
Relationships still account for something. Even in this day and age of seemingly selfish times.
