Wyotech and all of those highly advertised, overly expensive trade schools aren't all they are cracked up to be. I worked in a body shop for a few years during school. I got the job by stopping by and striking up a conversation with the boss, and went in part time pushing brooms and doing little odds and ends. I had zero body work experience, and by the time I left, I had learned enough to do some pretty extensive repairs. While I was there, they hired one of the Wyotech kids, and he was horrible. If you want to do mass production dealership repairs, you can do that. If you want to do reputable custom, get in a magazine type of work, your not going to get that going to wyotech.
At the shop I was at, they hated hiring people that had gone to these trade schools because they came in thinking they were great body men because they had 18 months of schooling. Your butting heads with people right away, and it causes some friction. Then we would spend months breaking them of there incorrect techniques and teaching them the right way to do things. They would rather have someone with zero experience that they could train at there shop to do things the way they want them done.
(The statement 'those who cant, teach' applies here. Why do you think the instructors at Wyotech are instructors? They couldnt hack it in the production side of the business)
And you are correct on one thing, you will be 30k$ in debt and still come in the door making 7-8$ an hour. So my advise would be, if autobody is something that interests you, find a shop in your area that has done some cool work, has been in magazines, has a reputation, and go in and tell them that you want to learn the trade, and your willing to start at the bottom to learn it. Put in some OT or some weekends if there open and learn all you can. If your hard working and have some skill, you will be moving up in no time, and you will learn alot more in a lot less time, and you wont be shelling out tons of cash.
On a side note, I went to school and got an electrical engineering degree, and like many have said, its fun working on your own car, but sucks working on everyone elses car. When you work on cars all day, the last thing you want to do when you go home is work on cars. Its nice to go to work and come home and have money and time to work on making your car better.
