I work as a Automotive mechanic and have for 32 years now.
Over the years I think I have worked on about every car made that is running around here in the US. It has been a good career over the years, I managed to earn enough to rais 5 kids and my wife was able to stay home all these years. From time to time I have taken breaks from cars and did computer work but that was WAY BACK in the early days of PCs when they needed work ALL THE TIME.
Deep down I hope to stop repairing cars and trucks some day but I think it will be my bread and butter for many years to come, unless I invent something really cool that EVERYBODY NEEDS.
By the way if you ever have any car/truck questions? I would be more then willing to help from time to time.
