Glad to have someone on the forum that's mechanically inclined, I guess you'll be doing some jobs on your civic yourself? Or are you planning to send it all to your mechanic?
My uncle is a master ase tech for over 40 years but he lives so far away that I don't get the chance to use his shop or even know-how. I just get lucky if he happens to visit while I need something done to the car.
I have zero formal training but began working on my cars since I got tired of mechanic dealership bs where basically, I didn't trust any of them and got to the point where if they wouldn't let me watch as they worked on the car, I wouldn't give the work.
It all became a big headache and always being handy, just started working on the cars myself.
Right away I was changing engine oil, transmission oil, differential oil, engine coolant, brake fluid, all fluid, air, and fuel filters, brake pads/ rotors etc. and eventually got to the point where I was replacing radiators, condensers, thermostats, hoses, spark plugs, accessory belts, door locks, door handles, window actuators, radiator fans, relays, headlights, sway bars....etc on family and friends' cars. Basically, these things are super simple and just bolt right on/ off. I never rebuilt an engine or even pulled one (but thankful as I never needed to). I also had more experienced friends help when working on cars where we were replacing the timing belt. Never wanted to take those kinda chances.
I never charged a single dollar working on anyone's car. It's either they're family or very close friends and I just help them out if I could find the time.
Noticed that it was not only fun, but I could do things on my time and not have to make an appointment and wait for hrs in a boring waiting area. Further, I always take my time and double or triple check things and even end up cleaning the areas that I'm working on where the dealers always leave things dirtier than they receive. If some oil splashes as they drain the fluids, they never take a rug and decreaser and clean things up.
From my experience, one just considers themselves lucky if all paid for work is actually getting done and no unnecessary work is recommended. I can't even begin to explain the thousands of dollars in work the dealerships recommend/ scare unknowing customers into doing that's completely not recommended by the manufacturers and just adds to the dealer bottom line.
Working on my own cars, I must admit that I accelerate and do things on shorter intervals than recommended in the manuals but it costs me just the price of the parts and some free time on a slow weekend.
