Good read.
I guess I'll throw my 2c in.
Like most of you, I tend to build and maintain my own rigs. Like some of you, I also spent a lifetime professionally wrenching.
Personally, I live to modify stuff. I choose something that fits my current platform and over time (while I use it) modify it into what I want. My specialty with GM was electronics. I got to watch all the manufactures go through a "learning curve" from the 80's through the 90's and into the 2000's when it came to electronics in cars. Because I was on the ground floor with this stuff, I'm very OCD on what I choose.
I have thrown money at a few different types of rigs trying to mold it into my version of what I want. What I hate is having to put money into a rig to fix the poor engineering done by the manufacture. I bet I spent several thousand dollars on my 04 TJ to make it correct. I purchased that because I was sick of reengineering my older Jeeps.
Now I've come full circle. Back to Toyota. My off-road rig is an older Cruiser and my every day is a new Tacoma. Most likely, those will be the last two vehicles I own. My cruiser has around 15k invested including a new motor and what I paid for it. My Tacoma (4WD SR5) is $290 a month.
My comment on the quality of technicians.
I started working for GM in 79. I had been going to school to get my EE degree but, life sometimes gets in the way. I find myself at a Chevy dealer. 4 year later, I'm a certified GM tech and I'm struggling. Back to school (part time nights). A few years later I finish and I realize, out of the 10 guys in the shop, only one actually knows what he's doing and its not me.
Fast forward to present. Finished my degree and now I teach. What I have learned over the years (and I pound this into my students) is, it doesn't matter what type of shop (independent, dealer) it's how the guy was trained and his attitude.
What you have is an industry where people think its easy to work on cars. Look into history. How much knowledge did you need to work on cars in the 40's. very little. He trains a guy in the 50's who trains a guy in the 60's.... and so on. Did any of them actually get proper training...NO.
When I read about people getting ripped off, I feel sorry for them. At the dealer, I had access to the latest equipment and the best info on what I was working on. I cringe when I think about PEP Boys or Firestone working on a newer vehicle. For example. On my TJ, I have the factory service manual. Its 2 main books and 5 supplement. It takes up about 8 inches of my book case. Go to an auto parts store and look at a manual. Its 1 inch thick, covers 5 years of TJ and Cherokee. The electronic versions (Mitchell, All Data, Shop key) are the same. How can you properly diagnose without the proper info. You Cant! Add in little or poor training in an environment where your not allowed to be wrong....ever.
Bottom line. How good is the technician? It depends on 1. his training 2. his environment (knowledge base and modern equipment) 3. attitude.
It may surprise some of you but in all my years, only a few people I have met, in my opinion, should be working on cars.
Remember. You need to be certified to cut hair. You don't need to be certified to do brakes....Brake's kill people! Bad hair just makes them angry.
Damn, did I just type all that.
