Around 100.
This is why it's good to have some car knowledge.
Also helps to have a trusted personal mechanic.
I had a car problem once.
Forgot what the issue was but I took it to a shop that my dad recommended.
They wanted to charge me 800 to fix it.
I took it to my mechanic, whom I should have gone to in the first place, who told me what the problem actually was, and charged less than 100 to fix it.
I told my dad, the people at the shop (where he's gone to fir years) are probably getting over on him.
His car is always in the shop
