Here's my 2 cents on the subject.
I went through two years of school at my local community college and will be getting my automotive technology degree this month, with the intent of being mechanic for my career. Now, in September I am moving and going to a real university to get a bachelors in construction managment.
My reasons for not staying in the automotive field:
-The economy sucks right now and shops are closing left and right.
-The shops that are open, there is little work and techs fight over work.
-They sway you in saying you can make $100k a year, but in reality that probably wont happen, as most of the techs in my shop only made in the low $20/hr range.
I worked at a Dodge dealership until Friday which was our last day. Now we are closed and most of the employees are unemployed. An ASE certified tech who was with the company for over 20 years only made about $22/hr.
But on the bright side. By the time you are out of school hopefully the economy will be better. And if its what you really love doing, and then you should do it if you dont mind not making as much as other careers would.
