JimW...Like you, I worked for GM during my college days. My uncle owned the largest Buick dealership in Cleveland when I was going to college in Kent. He allowed me to stay with him and the family, so I could go to Kent at resident rate and he gave me a job in the evenings and weekends working on cars. I have accumulated probably at today's prices over $20,000.00 in tools, including some electronic instruments that are seldom used today like a dwell/tach and a timing light. All my tools are Snap On and Macke, which as you know are the Cadillac of the tool industry for auto mechanics. I almost was talked into getting my master's mechanics license, but stayed in school and got my engineering degree.
I still do most of my own work, including on my kid's and Grandchildren's cars. It's not like it used to be when there was plenty of room under the hood to take care of business and some of the models today, the mechanic has to have a "special" tool that the dealership only has access to, so that the mechanic can do the job more easily. Because I was treated like an apprentice, I was not paid flat rate, just hourly rate. But, I know some of the line mechanics made huge salaries. Like you said, some mechanics could make 50-60 hours of pay for a 40 hour work week. The only think that I never got any experience on is automatic transmission work. Those things have a thousand pieces in them and they are very complicated, if you do not have the experience.
The dealership mechanics in Cleveland belonged to a union back in the day. How it is today, I don't know. I really enjoyed working on those big Electras and Wildcats. The Rivieras were a bit harder to work on because they had that short front end with the big engine. I remember working on the Buick engines. Man, they were huge. The Wildcats had that '401 and '425 engine in them, but there was still plenty of room to work on them because of their huge front end.
I worked for Ford and Jaguar dealers when I was in the trade. I also did a few years with an independent garage along with an awful lot of side work. There was a time myself and a buddy that I did my side work with, who also worked at the Jaguar dealer, were thinking about opening a garage together, but he was offered a service manager position at the Jag dealer and he accepted it. We still did side work together, but he didn't want to open a garage at that time. About a year later when the economy went bust in 1989, I along with 8 other Jag mechanics were laid off, they went from 14 Jag mechanics down to 6 in two months. I needed a job and went to work for Goodyear for two more years, but Goodyear sure wasn't Jaguar and my taste for the mechanics trade in general soured. I quit Goodyear and took my toolbox over my friend's house where we did all of the side work and decided to look at other avenues of work while paying the bills with the side work. That's when I ended up in the HVAC and air movement business with the company I'm with now. I took a shot and it worked out, I've been here for 25 years.
I too had thousands of dollars of tools, around $12-15K or so worth back then, so just about what you had. They too were all top of the line tools, Snap-On, Matco & Cornwell. Oddly enough my first ever wrench set I purchased when I was 14 years old was Craftsman and I still have it today. When I knew I was done with mechanics for a job, I sold all of my specialty tools and air tools. I had all of those Fluke multi-meters, dealer specialty tools, etc, but they weren't doing me any good sitting in my basement. I kept most of my hand tools and still have them today. I don't do any work on any of my cars anymore unless it's something I can do quick in my driveway. I have a couple friends that are still in the trade and if I ever need non-warranty repairs I can count on them.
I also never got involved with transmission work other than fluid and filter changes and replacing clutches. Most shops either had a transmission guy or sent their tranny work out because they are a completely different animal.
I'm not sure if there are unions in the dealerships or not these days, there weren't any that I knew of when I left the trade. The Goodyear shop I worked at was union. It was part of a Teamsters local but that was pretty much a joke, we paid our dues but never heard anything from the union itself. I didn't ask too many questions about it cause I knew I wouldn't be there too long.
There was nothing like working on the older cars, pre electronic ignition. It was a lot of fun building drag cars with my buddies and racing on Sundays. I also loved the classic cars. I was part of a 3 man team that restored a 56 Chevy Nomad that placed 3rd in it's class in the Nomad Nationals back in 1985.
