That's great I started fixing mopeds when I was a teenager and I learnt a lot about fixing car's from a close friend
I'm self taught myself and I definitely hear what you are saying about trusting mechanics I only use one car garage to get stuff done and sometimes I just do the repairs myself
But saying that my current car is very reliable
Only thing I've had to do service and change tires and brakes nothing to major at all
My last car got rit off parked outside of place
It was lucky that I could buy a new car two days later
Because the Insurance doesn't pay out straight away
Ok I hope you enjoy your day 🙏🏾
