Argument by analogy is a worthless pursuit every time you think of doing it please take a deep breath and think of a more honest useful argument.

Your car doesn't contain a full copy of most of the pertinent private information about your life and a copy of every private conversation for the last decade. Everything from your taxes to what kind of sex you enjoy.

Furthermore the blood would be evident just by casual examination whereas this suggests a fishing expedition.

Furthermore the mechanic would just be a good Samaritan rather than a paid agent of the government.

The relationship herein creates legal issues and a perverse incentive. Your repair tech shouldn't be acting as a government agent, shouldn't be paid for finding dirt on you, shouldn't be fishing, and shouldn't be the judge of what constitutes illegality especially when guessing wrong ruins someone's life.

I think this might be a response to some other comment, or perhaps a straw version of my comment, since I agree with basically everything you've written, especially the part about analogies.
