when i was training and doing my apprenticeship (nearly 18 years ago now) we didn't need to do any courses other than the first years worth of basic engineering and college and then we were supposed to go into the dealerships and get cracking

things have changed a lot since then now and you are going to get stuck in the position wehre you will be "qualified" but have no "experience" which means no one will take you on
alternativly, i have "expereience" but no "qualifications" so i'm fucked too

to be honest though, it's long hard work and you never get the smell of grease and oil out of your body, added to the fact that you boogies come out black when you blow your nose and your fingernails are constantly dirty and it's not something you want to start doing when you are enarly 30 with a mortgage to pay

fair play for trying and this isn't a post to tell you not to bother, but go in with your eyes open rather than think you can swan in and start spannering on day one and love it for ever

there are also loads more diagnostic tools to use nowadays so you've got to be able to figure out how to use them too, and don't forget that you may not be able to gain access to them straight away

i was spannering since i was about 6 so i had a fair bit of experience before i started my apprenticeship but even then, when my dad's mate was telling me how to do stuff it was still plugs and points, fuel injection hadn't really started then and cars were still using cart springs and no one had air con or any of the fancy gizmo's most cars now come with so you will be getting in at the deep end
