Working in the automotive industry

[mooseman]

Hi there, I'm turning 25 in August and am fed up with a white collar job working behind a desk in admin. I want to get some sort of career behind me and have always had a passion for cars to figured doing some sort of automotive apprenticeship would be best.

My brother is a qualified mechanic, my dad is self-taught but just as good.
Two of my uncles are diesel mechanics and one is a panel-beater.

I really have no idea what area is the best to go into. I've thought of;

Diesel Mechanic
Car Mechanic
Auto Elec

I'm not really keen on panel beating. I've got an IT/Admin background but have a pretty good understanding of mechanics and auto electrics already. I can do all the basic stuff and basic diagnosis.

As I'm 25 in August I can qualify for an adult apprenticeship and won't be getting as little money as I would be.

Anyone have any tips or advice?

I'm looking for something that has the best earning potential and career. I should be able to get a diesel or motor mechanic apprenticeship easy enough but I was hoping to get into a bigger dealership rather then a small place.
