That happened to me too when I was in my early 20s and just starting out. I got a "union" job at the airport as ramp agent. Those are the guys who handle the aircraft on the tarmac, unload and load baggage, flush out the lavatories, wave it in with the glow-sticks, etc.
Anyway I got paid something like $12.37 an hour which was good money back in the day. We are talking about 30 years ago. But I ran into issues quickly because I worked too fast. I had just come out of the Marine Corps and was full of energy and work ethic. I didn't believe in standing around with my hands in my pocket.
People used to sidle up to me and say "Don't kill the job, man". Because if everybody worked as hard as me, they'd only need about half the workers! Finally, I was politely informed by the "chief" that this line of work was not for me and when I got to my car that night, two tires were flat. I took the hint and went on to bigger and better things.
Anyway, so as not to totally hijack the thread with that story, I pretty consistently put 200,000+ miles on my Nissan cars (both Maxima and Altima models). The secret is to have all the recommended service done at the dealership - at the proper intervals by Nissan-certified techs. Many people think dealer service is a waste of money because you can go to Jiffy Lube for oil changes and have your other repairs done at "Joe's auto repair" down the street for a lot cheaper. But that has not been my experience at all.
I had a similar story with the Maritime Union.
