If one wants to be a mechanic (or anything in life) one needs a
credential. Mechanics have ASE Certification, doctors have MD degrees,
scientists PhDs etc. That's what's needed to get in the front door!

Yes you can "make a living" without a credential but one is often at a
disadvantage as others with the credential jump in front those without
the credential. A secondary, cap-in-hand position isn't a winner - ever.

A youthful shortcut will relegate a lifetime of work to second class
wages. That's not what you wanted to read but is the truth so don't take
that shortcut. Mercedes and all cars are increasingly complex and beyond
may of us who grew up in the 1950s and easily understand those simple,
old cars. That's history, your life is the future don't shun the future
act to take advantage of its opportunities. There's currently a shortage
of automobile mechanics - my local M-B dealer even seeks mechanics in
its mailings to us owners!

Cars are not the only mechanic jobs. Diesel mechanics, construction
equipment, air conditioning (auto, and commercial) railroads, aircraft
engines and aircraft all require certified mechanics. An FAA certified
mechanic is a good job.
